Gearwrench 84762 Bolt Extractor Socket 12mm 3/8 Drive

Product Description

The GEARWRENCH 84762 is a 12 mm bolt extractor socket designed to remove damaged, rounded, or seized fasteners that standard sockets can no longer grip. Built for 3/8 inch drive ratchets, this socket measures 1.377 inches in overall length and weighs 0.13 pounds. The extractor geometry bites into the outer surface of a compromised bolt head or nut, transferring torque directly to the fastener rather than to its edges. This tool is a standard addition to the service bays and toolboxes of mechanics, HVAC technicians, plumbers, and electricians who routinely deal with corroded or overtightened fasteners.

The 84762 is suited for both residential and commercial service work where 12 mm fasteners are common. Typical applications include removing rounded fasteners on HVAC equipment panels, plumbing fixtures, electrical enclosures, and general mechanical assemblies. It works with any 3/8 inch drive ratchet, breaker bar, or torque wrench, making it straightforward to integrate into an existing drive set. This socket is sold individually and is intended as a direct replacement or supplemental tool for technicians who need a dedicated extractor in the 12 mm size.

Installation Notes

Bolt extractor sockets are installed by hand tool technicians across HVAC, plumbing, electrical, and mechanical trades. Before use, secure the workpiece and power down or depressurize any system the fastener is part of. Apply penetrating oil to severely corroded fasteners before attempting extraction to reduce the risk of fastener breakage. Do not use an impact driver with this socket unless the tool is explicitly rated for impact use.
