Screw Extractors for Removing Broken and Stripped Fasteners

Screw extractors rescue stripped, broken or seized screws and bolts. Having the right extractor set and technique can save time and prevent damage to workpieces during removal.

Extractor types and best uses

Extractors commonly come in tapered spiral or straight fluted designs. Spiral extractors bite into the damaged fastener, while straight fluted extractors can provide stronger engagement in some metals. Select sizes that correspond to the fastener diameters you expect to encounter and consider left-hand drill bits for initial preparation.

Technique and buying tips

• Drilling first: create a centred pilot hole to improve extractor grip.
• Appropriate torque: use steady, controlled force to avoid breaking the extractor.
• Set range: choose a set covering small screws to larger bolts.
• Material quality: hardened steel extractors resist fracturing under stress.
• Complementary tools: centre punches and lubricants aid extraction success.

Clearance or refurbished extractor kits can offer value, but inspect threads and tips for wear. With careful preparation and the right extractor, you can often remove problematic fasteners without resorting to destructive methods, saving time and preserving the surrounding material.
