Gearwrench 86075 Bolt Extractor Socket 1/2 in Drive 21mm

Product Description

The GEARWRENCH 86075 is a bolt extractor socket designed to remove damaged, rounded, or corroded fasteners that standard sockets can no longer grip. Built for a 1/2 inch drive, this socket fits 21 mm and 13/16 inch screw heads, covering both metric and SAE fastener sizes in a single tool. At 3.23 inches in overall length, it provides enough reach for most underhood, structural, and mechanical applications. Laser etched markings keep size identification legible even after extended field use. A square end drive allows use with a wrench or pliers when a ratchet is not practical. Licensed tradespeople and experienced mechanics reach for this socket when a fastener head has been stripped or otherwise compromised.

This extractor socket is suited for automotive repair, heavy equipment maintenance, and general mechanical work where corroded or damaged bolts are encountered. The dual-sized compatibility with both 21 mm and 13/16 inch fasteners makes it a practical choice for mixed-fastener environments. It is appropriate for use in both professional shop settings and field service where bolt damage is a common obstacle.

Installation Notes

Power down or lock out any equipment before attempting fastener removal on machinery. Select the appropriate size engagement for the fastener head before applying torque. When using the square end with pliers or a wrench, ensure a secure grip to prevent slippage. Bolt extractor sockets are intended for removal only and should not be used to drive new fasteners.
