Gearwrench 84773 Bolt Extractor Socket 17mm 3/8 Drive

Product Description

The GEARWRENCH 84773 is a 17 mm bolt extractor socket designed to remove damaged, rounded, or seized fasteners that standard sockets can no longer grip. It accepts a 3/8 inch drive ratchet and measures 1.377 inches in overall length, making it compact enough for use in tight engine bays and chassis work. The socket uses a reverse-spiral or hardened-bite internal geometry to grip deteriorated bolt heads as torque is applied. Mechanics, automotive technicians, and maintenance professionals keep this type of tool on hand for stubborn fastener removal without resorting to destructive methods.

This socket is intended for professional and trade use in automotive, light truck, and equipment repair applications. It is sized for 17 mm fasteners, a common size found on suspension components, brake hardware, exhaust systems, and engine accessories. The 3/8 inch drive interface makes it compatible with the most widely used ratchet and breaker bar size in automotive service. It is packaged as a single unit and is suited for both shop and field use.

Compatibility

Designed for use with 3/8 inch drive ratchets and breaker bars. Fits 17 mm fastener heads, including damaged or rounded bolts typically found in automotive and light equipment applications.

Installation Notes

This tool is used by automotive technicians and mechanical trades for fastener extraction. Before use, ensure the drive ratchet or breaker bar is rated for the torque required and that the socket is fully seated on the fastener head. Apply penetrating lubricant to seized fasteners before attempting extraction to reduce the risk of fastener breakage. Follow standard shop safety practices and wear appropriate hand protection when working with corroded or high-torque fasteners.
