SATRA S-TS13X Juego de llaves de vaso extractoras de tornillos de 13 piezas para tornillos y tuercas dañados, métrico 8-24 mm, acero cromo-vanadio

When a bolt head rounds off, most mechanics reach for a drill and easy-out—but this SATRA 13-piece set skips the drilling entirely. Each 1/2" drive socket is machined with reverse spiral flutes that bite into damaged, rusted, or painted fasteners and back them out with an impact wrench or ratchet. The set covers 8 mm through 24 mm, so you're ready for everything from brake caliper bolts to axle nuts.

Overview

The SATRA S-TS13X screw extractor socket set is a complete solution for removing rounded, rusted, or seized metric bolts and nuts. The 13 sockets are forged from chrome vanadium steel (CrV) and chrome plated for corrosion resistance, so they hold up in professional shops and home garages alike. Each socket features a tapered entry that slips over damaged fastener heads, while the internal reverse spiral flutes dig in as you turn counterclockwise. The result: a firm grip that transfers torque directly to the fastener, not the tool.

What stands out

• 13 metric sizes from 8 mm to 24 mm—covers the most common automotive and industrial fasteners.
