Gearwrench 84771 Bolt Extractor Socket 5/8 in 3/8 in Drive

Product Description

The GEARWRENCH 84771 is a bolt extractor socket designed to remove damaged, rounded, or seized fasteners that standard sockets can no longer grip. Built for use with 3/8 inch drive ratchets, this extractor targets 5/8 inch (16 mm) fasteners and measures 1.377 inches in overall length. The compact profile allows access in tighter spaces where larger extractors cannot seat properly. Technicians working in automotive, mechanical, and general trade applications reach for this tool when conventional removal methods have failed and fastener damage has compromised the drive surface.

This bolt extractor socket fits standard 3/8 inch drive ratchets and breaker bars, making it compatible with tool sets already on most service carts. It is sized for 5/8 inch (16 mm) fasteners commonly found in engine components, suspension hardware, and structural assemblies. The 1.377 inch length suits moderate-depth fastener access without requiring an extension in many applications. Suitable for use in automotive repair shops, fleet maintenance environments, and general mechanical service work.

Installation Notes

This tool is typically used by automotive technicians, mechanics, and general trade professionals. Before use, ensure the fastener and socket are free of debris to allow the extractor to seat fully. Apply steady, controlled torque with the ratchet or breaker bar — avoid impact drivers unless the extractor is rated for impact use. Penetrating lubricant applied to the fastener threads prior to extraction can reduce the risk of fastener breakage.
