Quick verdict
Ten carbon steel extractors in five sizes with quarter-inch hex shanks: a burnishing end that cuts a seat in a stripped head and a reverse-spiral end that bites and backs the screw out in reverse drill. For deck repairs, where corroded and stripped screws are every third one, a set like this saves a day of drilling and plugging. Carbon steel bites hardened deck screws but will snap if forced; go slowly with the drill in reverse.
Strengths
- Five sizes cover deck screws from small trim screws to lag bolts
- Hex shanks fit any drill or impact driver chuck
- Double-ended: burnish one end, extract the other
- Heat-treated carbon steel grips stripped and rusted heads
- Ten pieces, so a broken extractor is not the end of the job
Weaknesses
- Carbon steel extractors snap if forced; hardened screws test them
- Does not help once a screw has sheared below the surface
- Spiral extractors can wedge and widen a hole if misused

The Screw That Will Not Come Out
Replace a few deck boards and the screws fight back: heads stripped by years of grit, shanks rusted into the joist, a Phillips recess that is now a round hole. A screw extractor set is the answer. Wolfride’s kit is ten carbon steel extractors in five sizes on quarter-inch hex shanks, each with a burnishing end that cuts a seat in the damaged head and a reverse-spiral end that bites and backs the screw out.
This review is based on the listing specifications and on how spiral screw extractors perform on deck and outdoor fasteners generally. We have not used this set ourselves and the brand is a generic importer.
How Extractors Work
Chuck the burnishing end, run the drill forward slowly and cut a clean cone into the stripped head. Flip the bit, set the drill to reverse, press and run slowly. The left-hand spiral digs into the cone and, because it tightens as the drill turns backward, it grips harder the more the screw resists until the screw turns out. On a deck repair this replaces drilling the head off and chiselling the shank.
Sizes
Five sizes run from small trim screws through standard #8 and #10 deck screws to lag bolts. Matching the extractor to the head matters; too small and it spins in the cone, too large and it will not seat. Having two of each in the set means a broken extractor does not stop the job.
Technique and Limits
Extractors are carbon steel and deck screws are hardened. The extractor wins when it bites a clean cone at low speed with firm pressure. Forced at high speed, or against a screw rusted solid, the extractor snaps. Soak rusted screws in penetrating oil first, go slowly and increase pressure gradually. Once a screw has sheared below the surface, a spiral extractor has nothing to grip and a plug cutter or hollow extractor is needed.
Beyond Decks
The same bits remove stripped screws from gates, furniture, engines and electronics, which is why a set lives in most toolboxes.
Who Should Buy It
- Anyone repairing a deck with corroded or stripped screws.
- Homeowners with a gate or fence full of rusted fasteners.
- DIYers who have ever rounded a screw head.
Common Owner Complaints
Extractors snapping in hard screws. Slow down, oil the screw, press steadily.
Alternatives to Consider
Speed Out and Grabit are the branded originals of this design. A hollow screw extractor handles sheared shanks. Locking pliers work on heads that stand proud.
Verdict
For the stripped and rusted screws every deck repair turns up, this ten-piece set backs them out for a few dollars, provided you work slowly in reverse. Keep it with the deck tools and the next stubborn screw is a two-minute job.

Chuck the burnishing end, run the drill forward at low speed to cut a clean cone in the stripped head. Flip to the extractor end, set the drill to reverse at low speed and press firmly; the spiral bites and backs the screw out.
Match the extractor to the screw head: #1 for small trim screws, #2 and #3 for standard deck screws, #4 and #5 for lags and bolts.
Too much speed or pressure, or a screw rusted solid. Go slower, add penetrating oil and let it soak, and try again. Carbon steel is tough, not indestructible.
A sheared screw below the surface needs a plug cutter or a hollow screw extractor, not a spiral bit.
