Gearwrench 84766 Bolt Extractor Socket 13mm 3/8 Drive

Product Description

The GEARWRENCH 84766 is a 13 mm bolt extractor socket designed to remove damaged, rounded, or seized fasteners that standard sockets can no longer grip. The socket uses a 3/8 inch drive and is sized for 13 mm screws and bolts. It is built for use with any standard 3/8 inch drive ratchet, making it compatible with tools already on most technician carts. Mechanics, HVAC service techs, plumbers, and general trade professionals reach for extractor sockets when corrosion or overtorquing has stripped a fastener head beyond what a conventional socket can handle.

This extractor socket fits into the standard workflow of any service call where fastener removal has become an obstacle. It is suited for use on mechanical equipment, HVAC units, plumbing fixtures, electrical enclosures, and automotive assemblies where 13 mm fasteners are common. The 3/8 inch drive format keeps the profile compact enough for confined spaces while still accepting the torque needed to back out a stubborn fastener.

Key Features

• Sized for 13 mm fasteners including rounded and damaged bolt heads

Compatibility

Designed for use with 3/8 inch drive ratchets and is sized to extract 13 mm fasteners. Compatible with standard 3/8 inch drive extensions and accessories.

Installation Notes

Always de-energize, de-pressurize, or otherwise make safe any system before attempting fastener removal. Install the extractor socket onto a 3/8 inch drive ratchet or breaker bar and seat it fully over the damaged fastener before applying torque. Apply steady, controlled rotational force rather than sharp impacts when possible to reduce the risk of fastener breakage. If the fastener is heavily corroded, applying penetrating fluid and allowing adequate soak time before extraction is standard trade practice.
