The Proto J7312 deep impact socket features a 1/2-inch drive and 3/8-inch opening with a 12-point configuration, providing multiple engagement positions for faster fastener access in tight or awkward spaces. Built to Proto's professional standards, it delivers the extended reach needed to fully seat on recessed or studded fasteners.
Designed for use with impact wrenches and drivers, this deep socket is ideal for automotive, industrial, and MRO applications where standard-depth sockets fall short. The 12-point design ensures reliable torque transfer and quick positioning even in confined work areas.
