Gearwrench 84772 Bolt Extractor Socket 17mm 3/8 Drive

Product Description

The GEARWRENCH 84772 is a bolt extractor socket designed to remove damaged, rounded, or corroded fasteners that standard sockets can no longer grip. Built for 3/8 inch drive ratchets, it targets 17 mm fasteners and measures 1.377 inches in overall length. The extractor socket uses a reverse-spiral or hardened-grip internal profile to bite into compromised bolt heads and stud surfaces, transferring torque efficiently without slipping. This tool is used by automotive technicians, fleet mechanics, and general maintenance professionals who regularly encounter seized or stripped hardware in the field or in the shop.

The GEARWRENCH 84772 suits a wide range of 17 mm fastener removal tasks in automotive, light truck, and equipment maintenance applications. It is intended for use with any standard 3/8 inch drive ratchet, breaker bar, or impact-rated extension. Typical scenarios include removing stripped lug nuts, damaged suspension bolts, and rounded engine fasteners where a conventional socket would spin free. It is sold individually, making it a practical single-size addition to an existing extractor set.

Installation Notes

Installation of a bolt extractor socket is performed by automotive technicians and general mechanics. Before use, secure the vehicle or equipment and ensure all relevant systems are depowered or de-pressurized as appropriate for the repair. Seat the extractor socket fully over the damaged fastener before applying torque to prevent cam-out. Do not use an impact driver at high torque settings unless the socket is rated for impact use, as this can fracture the extractor or the fastener.
