Gearwrench 80163 Hex Bit Socket 1/4 in Drive 3 Mm

Product Description

The GEARWRENCH 80163 is a hand hex bit socket designed for use with 1/4 inch drive ratchets and accessories. It accepts a 3 mm hex bit and delivers a secure, positive engagement on hex fasteners in tight or recessed locations. The socket measures 1-17/32 inches overall length with a 0.984 inch bit length, making it well suited for close-quarters fastener work. Constructed from steel with a chrome finish, the 80163 meets ANSI and ASME B107.5M standards. It is a compact, single-piece hand tool used by mechanics, HVAC technicians, electricians, and plumbers wherever hex-drive fasteners appear in equipment assemblies.

The 80163 fits standard 1/4 inch drive tool setups and is used across residential and light commercial service work. Typical applications include equipment panels, appliance assemblies, electrical enclosures, and HVAC unit fasteners that require a 3 mm hex drive. The compact overall length allows use in confined spaces where larger sockets or L-keys cannot fit. This socket is appropriate for both bench work and field service calls.
