Gearwrench 84754 Bolt Extractor Socket 5/16 in 1/4 in Drive

Product Description

The GEARWRENCH 84754 is a bolt extractor socket designed to remove damaged, rounded, or seized fasteners. It accepts a 1/4 inch drive ratchet and is sized for 5/16 inch (8 mm) screws and bolts. The extractor socket uses a reverse-spiral or fluted internal profile to bite into compromised fastener heads as torque is applied, giving technicians a reliable grip where standard sockets fail. Weighing just 0.08 pounds, it is a compact, single-piece tool suited for tight spaces in HVAC equipment, plumbing fixtures, electrical enclosures, and general mechanical repair work.

This extractor socket is appropriate for residential and light commercial service work where fasteners have been stripped, corroded, or otherwise damaged. It is compatible with 1/4 inch drive ratchets and extension bars, making it easy to integrate into an existing socket set. Typical applications include panel removal, equipment access cover fasteners, and any job where a 5/16 inch fastener head has degraded beyond the reach of a standard socket. The 8 mm sizing makes it equally useful in metric-fastener applications of the same diameter.

Installation Notes

De-energize or shut off any equipment before attempting fastener removal on live panels or pressurized systems. Insert the extractor socket fully over the damaged fastener head before applying torque to ensure maximum contact. Use steady, controlled force on the ratchet — avoid impact drivers with this style of extractor socket unless the tool is rated for impact use. A licensed technician or trained mechanic should evaluate fastener condition before service to avoid further fastener or housing damage.
