Gearwrench 82551 Hex Bit Socket 3/8 in Drive 8mm

Product Description

The GEARWRENCH 82551 is a hand hex bit socket designed for driving 8 mm hex fasteners using a 3/8 inch drive ratchet or breaker bar. Built from steel with a chrome finish, it delivers a clean, corrosion-resistant surface that holds up in shop and field environments. The socket measures 6.14 inches overall length with a 5.39 inch bit length, giving technicians extended reach into recessed fastener locations. It meets ANSI and ASME standards, making it appropriate for professional trade use. This is a single-piece socket suited for mechanics, HVAC technicians, and general trades who regularly work with hex-head fasteners.

This socket fits standard 3/8 inch drive hand tools and is used across a wide range of service applications including HVAC equipment access panels, plumbing fixture hardware, and mechanical assemblies that use metric hex fasteners. The 8 mm hex size is common in light commercial and residential equipment. Its extended bit length is useful when fasteners are deeply recessed or when clearance is limited around the work area.
