Damaged Screw Extractor Kit

This 12-piece damaged screw extractor kit removes stripped, rusted or broken screws and bolts from 3 to 12 mm. It suits DIY users, contractors and anyone who needs a reliable way to free seized fasteners without damaging the surrounding material.

The extractors operate in reverse at low speed and require a pre-drilled hole of the correct size. They are limited to the 3-12 mm range and cannot grip fasteners outside that span or remove screws without a drilled pilot hole.

Questions about this item

Which screw extractor set should I choose for damaged screws?

This set includes six extractors covering screw and bolt sizes from 3 to 12 mm, plus an extra #2 bit for the most common size, all stored in a durable case.

What does the 63-65 HRC hardness mean when I use the tool?

The high-speed steel 4341 bits reach 63-65 HRC, so they stay sharp and resist wear while drilling into hardened, rusted or stripped fasteners.

What drill interface do these extractors need and what does it limit?

They work with any standard drill in reverse at low speed; the two-step drill-then-extract method caps the process at manual control rather than high-speed power.
