Introduction

AMSUO 5-Piece Screw Extractor Set (EXT-5) — Milled 40Cr Alloy Steel, Reverse Spiral Flutes, Hex Shank, for Broken Bolt & Stud Removal, 10-Year Warranty

Professional 5-piece screw extractor set machined by precision milling from solid 40Cr alloy steel — a step up from ordinary threaded (screw-type) extractors. Milled construction delivers straighter, stronger, and more precise spiral flutes that bite into broken fasteners without snapping, even on seized bolts and studs. Black hex shanks fit wrenches, drill chucks and 1/4" quick-change systems. Retail blister pack with 10-year warranty.

Ground silver cutting edges — sharp engagement for fast, clean gripping
5 graduated sizes in one set — one kit covers common fastener sizes
