Gearwrench 84777 Bolt Extractor Socket 3/4 in 3/8 Drive

Product Description

The GEARWRENCH 84777 is a bolt extractor socket designed to remove damaged, rounded, or seized fasteners measuring 3/4 inch (19 mm). It accepts a standard 3/8 inch drive ratchet, making it compatible with a wide range of common drive tools already in a tech's kit. The socket measures 1.377 inches in overall length and weighs 0.21 pounds, keeping it compact for use in tighter access points. It is used by mechanics, HVAC technicians, plumbers, electricians, and general tradespeople who regularly encounter corroded or damaged fastener heads during service and repair work.

This bolt extractor socket is suited for residential and light commercial service applications where fasteners have become rounded or stripped due to corrosion, over-torquing, or previous tool damage. It works with 3/8 inch drive ratchets, extensions, and breaker bars. The 19 mm extractor size targets the common 3/4 inch fastener found across mechanical, structural, and equipment mounting applications in the trade.
