Proto J4712T Hand Socket 3/8 Inch 12-point 1/4 Drive

Product Description

The PROTO J4712T is a 3/8 inch, 12-point hand socket designed for use with a 1/4 inch drive ratchet or breaker bar. It features a standard-length profile and a chrome-plated finish that resists corrosion and makes it easy to wipe clean after use. The 12-point geometry engages fasteners at more rotational positions than a 6-point socket, which is useful in tight quarters where swing arc is limited. This socket is suited for general mechanical and maintenance work across HVAC, electrical, plumbing, and light industrial applications. It weighs just 0.04 pounds and fits easily into a standard socket tray or roll pouch.

This socket is appropriate for residential and light commercial service work where a compact 1/4 inch drive setup is preferred. Its standard length fits most applications where socket extensions are not required. Technicians working on equipment panels, access covers, junction boxes, and mechanical assemblies will find this size commonly encountered. The 3/8 inch size addresses fasteners found on a wide range of trade equipment and fixtures.

Installation Notes

This socket is installed and used by licensed HVAC technicians, electricians, plumbers, and general maintenance professionals. Always ensure the drive tool is fully seated and the socket is properly engaged on the fastener before applying torque. Inspect the socket for cracks or wear before use, and retire any damaged socket immediately to avoid fastener rounding or tool failure.
