The GEARWRENCH 84403 is a 3/8 inch drive hex bit socket designed for driving internal hex fasteners in mechanical, HVAC, plumbing, and general trade applications. The socket accepts a 1/2 inch hex bit and delivers a 0.58 inch bit length with an overall length of 1-31/32 inches, keeping the profile compact for use in tighter service areas. Constructed from steel and manufactured to ASME B107.33 standards, this socket is built to withstand the torque demands of professional fastener work. It is sold individually and is a direct fit for standard 3/8 inch drive tool sets.
This hex bit socket suits residential and commercial service work wherever internal hex cap screws or set screws need to be driven or removed. Common applications include equipment panel fasteners, pump and motor hardware, and structural fasteners encountered during HVAC, plumbing, and electrical service. The short overall length makes it practical for use in confined equipment compartments. Licensed technicians and service professionals across trades will find this socket a reliable addition to a 3/8 inch drive set.
Designed as an OEM-style replacement hex bit socket compatible with standard 3/8 inch drive ratchets, extensions, and torque wrenches used across trade applications.
This socket is installed and used by mechanics, HVAC technicians, plumbers, and electricians working with internal hex fasteners. Always ensure the drive tool and socket are properly seated before applying torque to avoid rounding the fastener or socket. Inspect the socket for wear or cracks before each use and replace if deformation is observed. No power source shutoff is required for use of this hand tool.
