Proto J7444 Impact Socket 1/2 in Drive 1-3/8 in 12-pt

Product Description

The PROTO J7444 is a 12-point impact socket designed for heavy-duty fastener removal and installation in professional trade environments. Built for use with a 1/2 inch drive impact wrench, it accepts a 1-3/8 inch fastener and measures 2.125 inches overall length. The compact profile suits tight-clearance applications common in HVAC equipment service, plumbing rough-in, and mechanical assembly work. Weighing 0.7 pounds, the socket is sized for portability without sacrificing the wall thickness needed to handle impact torque loads. Licensed mechanics, HVAC technicians, and plumbers rely on this type of socket for consistent performance on high-torque fasteners.

The J7444 fits standard 1/2 inch drive impact wrenches and is suited for use in residential and light commercial mechanical work. Typical applications include equipment mounting hardware, pipe flange bolts, structural fastener assemblies, and service panel or unit base hardware. The 12-point configuration engages fasteners at more positions than a 6-point socket, useful when fastener access is limited to a partial rotation arc.

Installation Notes

This socket is intended for use by qualified tradespeople operating pneumatic or cordless impact wrenches with a 1/2 inch square drive. Ensure the socket is fully seated on the drive anvil and the fastener before applying torque. Inspect the socket for cracks or deformation before each use, and do not use impact sockets with standard ratchet handles not rated for impact loads.
