Gearwrench 84752 Bolt Extractor Socket 7mm 1/4 Drive

Product Description

The GEARWRENCH 84752 is a 7 mm bolt extractor socket designed to remove damaged, rounded, or seized fasteners that standard sockets can no longer grip. Built for use with 1/4 inch drive ratchets, this socket measures 1.377 inches in overall length, keeping it compact enough for tight engine bays and confined service areas. The extractor socket uses a reverse-spiral or fluted internal geometry to bite into compromised bolt heads as torque is applied, driving the fastener out without requiring separate stud extractors or left-hand drill bits. It is a practical single-piece solution for technicians who regularly deal with corroded or over-tightened fasteners across automotive, HVAC, and light mechanical service work.

This extractor socket is sized for 7 mm fasteners and pairs with any standard 1/4 inch drive ratchet, extension, or breaker bar. It suits residential and light commercial service applications where smaller fasteners are common, including automotive trim hardware, HVAC cabinet screws, panel fasteners, and similar small-diameter bolts. The compact 1/4 inch drive format makes it well-suited for work in confined spaces where larger drive tools cannot fit.

Key Features

• Removes 7 mm damaged, rounded, or seized bolt heads
• Compatible with 1/4 inch drive ratchets and extensions
• Compact overall length of 1.377 inches for confined-space access
• Reverse-engagement design bites harder as more torque is applied
• Single-socket solution eliminates need for separate extraction tools

Compatibility

Designed for use with 1/4 inch drive ratchets, extensions, and drive tools. Fits 7 mm fastener heads including bolts and screws with that nominal diameter.

Installation Notes

Installation should be performed by a qualified mechanic or service technician familiar with fastener extraction procedures. Ensure the drive ratchet and all extensions are securely seated before applying torque to avoid socket disengagement. Do not use an impact driver with this socket unless the manufacturer explicitly rates it for impact use. Always relieve tension on the fastener when possible and apply penetrating oil to corroded threads before extraction to reduce the risk of fastener breakage.
