AMSUO 8-Piece Screw Extractor Set (Metric) — for 3–50 mm Screws

A professional 8-piece metric screw extractor set designed to remove broken, stripped, or seized bolts, screws, and studs fast. Each extractor features a hardened steel body with left-hand spiral flutes that bite into the broken fastener as you turn — the harder the resistance, the tighter the grip. Square drive ends fit standard tap wrenches and extractor handles. Retail-ready blister card with 10-year warranty.
