Proto J4710TB 5/16 Inch 12-point Hand Socket 1/4 Drive

Product Description

The PROTO J4710TB is a 5/16 inch, 12-point hand socket designed for use with a 1/4 inch drive ratchet or extension. Machined from alloy steel and finished in black oxide, this standard-length socket measures 7/8 inch overall length and weighs 0.03 pounds. The 12-point configuration provides double the engagement positions of a 6-point socket, making it useful in confined spaces where swing arc is limited. It meets ASME B107.110-2012 and SAE AS4984A standards and carries a lifetime warranty. Licensed HVAC technicians, plumbers, electricians, and mechanical contractors will find this socket suited to fastener-intensive service work.

This socket is appropriate for general mechanical service in residential and commercial maintenance applications. Its compact 1/4 inch drive sizing makes it a natural fit for light-duty fasteners encountered in panel work, equipment access covers, and component mounting hardware. The black oxide finish provides mild corrosion resistance for shop and field use. It is sold individually and is not tether capable, which should be noted for applications requiring dropped-object prevention.

Installation Notes

This socket is intended for use by mechanics, technicians, and trade professionals working on fasteners in the 5/16 inch range.
