Best Screw Extractor Sets in Australia (2026)

The screw does not budge. You lean harder, the driver skates out one more time, and what used to be a Phillips cross is now a shallow silver dish. The fastener has stopped being a fastener and started being a problem, and pressing down harder will not fix it.

A screw extractor set is the cheap insurance that gets you out of it: small, hardened, reverse threaded tools that bite tighter the further you turn anticlockwise. Australian homes serve up a specific version of this problem, with soft zinc screws in flat pack furniture, salt corroded bolts anywhere near the coast, and deck fixings baking in the same hole since the place was built. We looked at what is on Amazon Australia in September 2026 and settled on eight sets covering the range, from a chewed hex socket in a bookcase to a snapped bolt in an engine bay.

What is the best screw extractor set in Australia right now?

For most Australian households the answer is the Irwin Hanson 11119 10-Piece Spiral Extractor and Drill Bit Set. It gives you both halves of the job in one case: five spiral flute extractors and five matching left-hand drill bits, so you drill the pilot hole and back the fastener out without hunting for a second product.

For the most extractor sizes per dollar, the Neiko 01925A Screw Extractor and Left Hand Drill Bit Set is the value option, and the most reviewed product in this guide with almost four thousand owner ratings. Its left-hand bits are cobalt fortified high speed steel.

If the problem is a rounded out screw head rather than a snapped shank, the ENGINEER DBZ-20 Screw Extractor Bit Set is the cheapest pick here and the quickest fix for a flat pack furniture emergency: four bits on a 6.35 mm hex shank, made in Japan, straight into a drill or impact driver.

How do our eight screw extractor sets compare?

Prices below are Amazon Australia buy box figures captured while writing, and they move. Every set here removes broken fasteners; none cuts threads.

How we chose these screw extractor sets

NestPath does not run a workshop. We are an aggregator, so our job is to read the listing data honestly and say what it does and does not cover.

• We pulled the live Amazon Australia pool and kept only listings that state the extractor style, material and size range, because a set that hides its sizes cannot be matched to a broken fastener.
• We checked star ratings and review counts fresh at the time of writing and required real owner feedback, not a handful of ratings on a new listing.
• We spread the shortlist across the three mechanisms Australians need: spiral extractors driven into a pilot hole, damaged head bits that grip from above, and external sockets that bite a rounded bolt head.
• We dropped reseller priced outliers, thread cutting kits sold as extractors, and anything that would not confirm its brand.

Which screw extractor set should most Australian homes buy?

The Irwin Hanson 11119 is the safest single purchase because it removes the second shopping trip. Five spiral flute extractors sit beside five left-hand high speed steel drill bits in one case, and that pairing matters: a spiral extractor only works if the pilot hole is the right diameter, and a matched set makes that decision for you.

The bits are split point ground at 118 degrees with a straight shank, the geometry that stops a bit walking across a hardened screw head. Because they run left-handed, the fastener often spins itself out while you are still drilling, so you never touch the extractor.

The extractors are spiral flute, wedging deeper into the pilot hole as torque rises. Irwin states the flutes embed further into the metal under load, the difference between this style and a straight fluted easy out that slips once the hole polishes.

It is made in the USA and carries a manufacturer warranty, worth noting in a category full of unbranded kits with nobody behind them, and it pairs naturally with a starter home tool kit.

Flaws but not dealbreakers

It is the dearest of the three headline picks, and the ten piece count includes drill bits, so you get five extractor sizes rather than ten. There is no moulded insert holding each piece in a labelled slot, so mark the sizes the day they arrive.

Which set gives you the most sizes for the money?

The Neiko 01925A delivers the same drill-and-extract system as the Irwin at the value end of the range: five alloy extractors sized number one through five, plus five left-hand cobalt fortified high speed steel drill bits at 5/64, 7/64, 5/32, 1/4 and 19/64 of an inch.

The cobalt content is the interesting part in this band. Cobalt alloyed high speed steel holds hardness at higher temperatures, which matters because drilling a hardened screw generates heat fast and plain HSS loses its edge in seconds. The bits are ground at 135 degrees, a steeper point than the Irwin set, so they are less prone to walking on a polished head. With a decent cordless drill this is close to everything you need.

It is the most reviewed product in this guide, and the rating behind those reviews is the lowest of our eight picks at 4.0 out of 5. A set bought this widely collects a long tail of reviews from people who used a number four extractor on a fastener that needed a number two, and the listing is candid that the extractors are alloy rather than tool steel.

Flaws but not dealbreakers

The alloy extractors are the weak point next to the tool steel in the American made sets here, so they are likelier to snap if you lever sideways. Country of origin is China, and the case latches are the sort that eventually stop latching.

Which extractor works on a chewed out hex or Phillips head?

The ENGINEER DBZ-20 solves a different problem to a spiral extractor, and it is the one most people need first. When a hex socket screw cams out, the shank and thread are fine and only the head is broken, so drilling out the whole screw is wildly excessive. These four bits cut a fresh grip into the damaged head and back it straight out.

The bits are high carbon steel on a 6.35 mm hex shank, so they work in a bit holder, a drill or an impact driver, and each is about 104 millimetres long. Engineer designs them for hex socket heads, the fasteners you meet in flat pack furniture, bike components and appliance covers. The manufacturer notes that with a pilot hole drilled first they also work on Phillips, Torx and square drive heads.

It is made in Japan by a company that has built specialist fastener tools for decades, and it is the cheapest pick in this guide, so it is the least you can spend and still solve a chewed head. At 4.5 out of 5 it ties with the Mayhew set for the second highest star rating of our picks. If you have ever found an Allen key spinning inside a screw head mid wardrobe build, this is the tool that would have saved the afternoon. It lives beside a screwdriver set.

Flaws but not dealbreakers

Four bits is a narrow range, and they cannot touch a snapped bolt with no head left to grip. Treat it as the first tool you reach for, not the only extractor you own.

Which set bites a rounded bolt head from the outside?

The GEARWRENCH 84787 Bolt Biter works from the outside in, the opposite approach to everything above. Rather than drilling into the fastener, its four extractors grip the rounded flats of a bolt head or nut and turn the whole thing off, using tapered side and tip cutting edges.

What separates it from a generic bolt remover is that it is bi-directional. You can tighten as well as loosen, so a specialty fastener you cannot replace on a Saturday goes back in the same hole. GEARWRENCH claims the high strength steel construction gives up to fifty times the life of competing extractors, which is a manufacturer figure rather than an independent one.

Each extractor is short, at roughly 13 millimetres of working length, so it suits places a long spiral extractor and a drill will never fit: under a sink, inside a mower deck, behind a fence rail. Of our eight picks this one has the smallest body of owner feedback, at just over two hundred ratings, and it sits at 4.3 out of 5, a solid score from a real trade brand rather than a huge score from an anonymous listing.

Flaws but not dealbreakers

Four sizes will not cover a workshop, and this style is useless on a countersunk screw or anything sitting flush, because nothing is proud of the surface to grip. It is a bolt and nut solution first, despite the name.

Which set suits soft or thin walled parts?

The CRAFTSMAN CMMT14108 is five spiral screw extractors in a storage case, and the reason to choose it is written into the listing: it does not expand the material while it is working. That is the failure mode that ruins a repair, where a tapered extractor acts like a wedge and splits the part you are trying to save.

Aluminium engine covers, brass plumbing fittings, alloy bike parts and the thin steel of an appliance chassis all crack or bulge under a wedge. If your broken fastener sits in something you cannot easily replace, this is the mechanism you want.

Five extractor sizes cover both SAE and metric fasteners, useful in an Australian garage where an imported appliance, a Japanese car and a locally bought mower share one shed. It is hand powered, turned with a tap wrench or an adjustable spanner rather than a drill, and that slower pace is part of why it is gentler on the workpiece. It sits at 4.3 out of 5 across roughly sixteen hundred ratings.

Flaws but not dealbreakers

There are no drill bits in the box, so you supply your own left-hand or cobalt bits and size the pilot hole yourself, a real gap if this is your first extractor. Being hand powered also makes it slower when the material can take a drill.

Which set will still be in the drawer in twenty years?

The Mayhew Pro 37332 is the buy once option: five tool steel extractors, black oxide finish, made in the USA, and it is the only pick in this guide whose Amazon listing states a lifetime warranty. If you keep tools for decades, that line matters more than any spec.

The sizes are published individually, which is rare and genuinely useful. The 36961 takes a 1/8 inch drill for screws around No. 10 up to 5/16 inch, the 36962 takes 3/16 inch for 3/8 inch fasteners, the 36963 takes 15/64 inch for 7/16 inch, the 36964 takes 5/16 inch for 1/2 to 9/16 inch, and the 36965 takes 3/8 inch for 5/8 inch. You can check before buying whether it covers your bolt.

Tool steel with a black oxide finish is the combination you want in a coastal Australian shed, because black oxide holds oil far better than bright steel. The case is compact at about 9.7 by 7.6 by 1 centimetre, small enough to live in a toolbox tray permanently.

At 4.5 out of 5 it ties with the ENGINEER set for the second highest star rating here, backed by more than seven hundred ratings. Mayhew builds the line for fleet and plant maintenance, a fair signal of the abuse it absorbs.

Flaws but not dealbreakers

Like the CRAFTSMAN set it ships without drill bits, and sizing is imperial only on the listing.

Which set removes a broken screw in one pass?

The Alden 8440P Grabit Pro compresses the job into two steps with one tool. Each of its four bits is dual ended: a burnishing tip that cuts a clean seat in the damaged fastener, and a threaded extraction tip that grips and reverses it out. You flip the bit rather than swapping tools.

It runs on a 3/8 inch drill and the bits are high speed steel, roughly 105 millimetres long. Alden publishes the coverage bit by bit: bit one handles number 4 to number 7 screws and number 10 bolts at 5 mm, bit two handles number 8 to number 10 screws and 1/4 inch bolts at 6 mm. Overall it removes screws up to about 100 millimetres long and bolts up to 3/8 inch across hex, Phillips and square drive heads.

The appeal is speed. Working through a deck or a pallet of reclaimed timber where you hit broken screws repeatedly, flipping one bit is far faster than swapping between a left-hand drill bit and a spiral extractor forty times. It sits at 4.2 out of 5, the second lowest star rating of our picks, across more than thirteen hundred ratings, which reflects a tool with a real technique to it: too much drill speed burns the burnishing tip, and the extraction end needs steady downward pressure.

Flaws but not dealbreakers

The warranty on the listing runs only 90 days, and the dual ended design means a snapped tip costs you both functions of that bit at once. Keep drill speed low and let the tool work.

Which set do you want when the rattle gun comes out?

The GEARWRENCH 84783 Bolt Biter Impact Extraction Socket Set is the highest rated of our eight picks at 4.7 out of 5. Fifteen impact rated sockets across 1/4 inch and 3/8 inch drives, in black oxide alloy steel, built to be hammered by an impact wrench rather than turned by hand.

Where the smaller Bolt Biter grips a rounded head with hand torque, these sockets survive the shock loading of an impact tool, which is what you need when a bolt has rusted solid and hand torque only rounds it further. The double square drive geometry inside each socket bites the flats of a chewed hex head and keeps biting as load rises.

Fifteen pieces is the largest set count in this guide, and two drive sizes in one case is the practical part: 1/4 inch reaches a bracket or bumper fixing, 3/8 inch handles suspension and mower deck bolts. The set weighs roughly 370 grams. It is also the dearest pick here, and it assumes you own an impact driver or a rattle gun, so it makes no sense as a first extractor for someone whose worst problem is a stripped bookshelf screw.

Flaws but not dealbreakers

You need an impact tool to get value from it, and it does nothing for a screw snapped off flush. The black oxide spots with rust if sockets go back in the case wet, and country of manufacture on the listing is China despite the American brand.

Which screw extractor set should you buy?

Match the tool to the failure in front of you, not the size of the set.

What should you look for in a screw extractor set?

Start with the mechanism, because the three families solve different failures and buying the wrong one is the commonest mistake here.

Spiral flute extractors are the classic reverse tapered cones. Drill a pilot hole into the broken fastener, tap the extractor in, turn anticlockwise, and the spiral wedges deeper as torque rises. This is the only family that works when the fastener has snapped off below the surface, and it is what the Irwin, Neiko, CRAFTSMAN and Mayhew sets use.

Damaged head bits such as the ENGINEER set grip from above, cutting a fresh purchase into a head that has cammed out but is otherwise intact. Faster and less destructive, but useless once the head is gone.

External extractors and sockets such as the two GEARWRENCH sets clamp the outside of a rounded bolt head or nut. They need something proud of the surface to grip, and in exchange they never cut into the fastener at all.

Next, check whether drill bits are included. A spiral extractor is only as good as its pilot hole: too small and it cannot seat, too large and you cut into the parent thread and turn a small job into a thread repair. Matched sets like the Irwin and Neiko remove the guesswork. If bits are not included, buy cobalt or quality left-hand HSS, because a hardware store twist bit will glaze on a hardened screw before it cuts. Left-hand bits cut anticlockwise, so on smaller screws the drilling alone often spins the broken piece out.

Material is the last lever. Tool steel and high speed steel extractors are harder and less likely to deform, while cheaper alloy extractors bend before they shatter. A snapped extractor is the worst outcome here, because hardened extractor steel is harder than your drill bits, so you cannot drill it out. That is when a job becomes a machine shop visit.

Finally, extraction is not thread repair. If the parent thread is damaged or cross threaded you need a different tool, and our guide to the best tap and die sets in Australia covers thread cutting and chasing. Extractors remove the broken fastener; a tap restores the hole it came out of.

How do you look after screw extractors so they last?

Keep them dry and lightly oiled and they will outlive the house. Hardened steel is not stainless steel, and black oxide is a mild rust inhibitor rather than a barrier, so anything stored in a coastal shed will spot over a wet summer. Wipe each piece with a rag and a smear of light machine oil before the case shuts, especially after a job involving penetrating fluid or cutting oil, because those residues attract moisture.

Inspect the flutes before every use. A spiral extractor with a chipped edge will slip in the pilot hole, polish it smooth and leave you worse off than when you started. Retire chipped pieces, and never sharpen one on a bench grinder, because the heat draws the temper straight out of the tip.

Technique is maintenance too. Keep pressure square and axial, never sideways, because levering is how extractors snap. Where a fastener is truly seized, gentle heat on the surrounding metal breaks the corrosion bond far more reliably than force.

You'll also want

Extraction is rarely a one tool job. These items turn a difficult removal into a routine one.

• WD-40 Specialist Penetrant Spray to creep into a rusted thread. Apply, walk away for ten minutes, then try. This habit prevents more snapped extractors than any upgrade.
• Bosch 19 piece HSS-Co cobalt drill bit set covering 1 to 10 mm, for sets that ship without bits.
• Mulwark automatic centre punch to dimple the exact centre of the broken screw, because an off centre pilot hole is why most attempts fail.
• Tap Magic Industrial Pro cutting fluid for drilling hardened steel, which keeps the cutting edge cool.
• IRWIN VISE-GRIP locking pliers, 2 piece set for studs still proud enough to clamp, because the fastest extraction often never involves a drill.
• Stanley clear lens safety glasses, because hardened extractors fail suddenly and send fragments at speed.

The competition

Several other extractor sets sell well here and missed the cut.

The Bosch BSPE6D 12-piece set pairs spiral flute high carbon steel extractors with black oxide drill bits and has plenty of owner feedback, but its star rating sits at the bottom of our shortlist and high carbon steel is a step below the tool steel and high speed steel in our picks.

The Alden 4507P Grabit Micro uses the same dual ended mechanism as the Grabit Pro, sized for small screws in electronics work, but the Pro covers a far more useful range for a household kit. The Ontel Speed Out titanium kit is heavily marketed and cheap, and its owner rating is the weakest of anything we considered: four coated bits rather than a hardened core does not survive a rusted fastener.

The Irwin Hanson 53545 six piece set is the extractor only version of our top pick, but buying it means sourcing matched left-hand drill bits separately, which erodes most of the saving.

The Lisle 62900 set is a genuine trade tool, left out purely on scope, because it is listed under automotive parts rather than tools. We also skipped the unbranded five and six piece kits at the cheap end, typically the same casting under a dozen names, with no steel grade stated and nobody to contact when one shatters in a hole.

Screw extractor set FAQs

Do screw extractors actually work?

Yes, when they are matched to the failure and the pilot hole is right. A spiral extractor removes a fastener that has snapped off, a damaged head bit removes one whose head has cammed out, and an external socket removes a bolt head that has rounded. Most failures come from using the wrong family or drilling an off centre pilot hole.

What size drill bit do you use with a screw extractor?

Use the bit specified for that extractor size, which is why matched sets are worth the extra spend. As a rule the pilot hole should be roughly half the diameter of the broken fastener shank, large enough for the extractor tip to seat but small enough to leave material for it to bite. Cut into the parent thread and a simple removal becomes a thread repair job.

Can you use a screw extractor with an impact driver?

It depends on the extractor. Damaged head bits on a 6.35 mm hex shank, like the ENGINEER DBZ-20, are designed for a bit holder, drill or impact driver. Impact rated extraction sockets, like the GEARWRENCH 84783, are built for shock loading. Traditional spiral flute extractors are not impact rated and will shatter under a rattle gun.

What do you do if the screw extractor breaks off in the screw?

Stop drilling, because hardened extractor steel is harder than a standard drill bit and you will destroy bits without progress. Your realistic options are a carbide burr or solid carbide drill in a drill press, spark erosion at a machine shop, or drilling out the whole fastener and repairing the thread with an insert. Prevention is far cheaper: keep pressure square and go slow.

Is a screw extractor set the same as a tap and die set?

No, they do opposite jobs. A screw extractor removes a broken or damaged fastener from a hole. A tap and die set cuts or chases threads, restoring a damaged thread in the hole or on a bolt. A seized fastener often needs both in sequence.
