Proto J7344 Impact Socket 1/2 in Drive 1-3/8 in 12-point

Product Description

The PROTO J7344 is a 12-point impact socket designed for heavy-duty fastener removal and installation in trade and industrial applications. Built for use with a 1/2 inch drive impact wrench, it accepts a 1-3/8 inch fastener and measures 3.5 inches in overall length. The 12-point configuration provides additional engagement positions, reducing ratchet swing arc in tight spaces. At 1.54 pounds, the socket is built with the mass appropriate for absorbing impact tool energy. Mechanics, maintenance technicians, and field service professionals working on structural fasteners, heavy equipment, or fleet vehicles will find this socket sized for common large-hex applications.

The J7344 is suited for professional shop and field use where a 1/2 inch drive impact tool is the standard platform. Typical applications include heavy equipment service, fleet maintenance, industrial machinery work, and structural assembly or disassembly tasks involving 1-3/8 inch fasteners. The 3.5 inch overall length provides reach into recessed bolt locations without requiring an extension in many standard setups.

Installation Notes

This socket is intended for use by qualified mechanics and maintenance technicians familiar with impact tooling. Always confirm the drive retainer or hog ring is fully engaged before applying torque. Inspect the socket for cracks, rounding, or wear before each use and remove from service if any defects are found. Do not use impact sockets as substitutes for hand-tool sockets when using manual torque wrenches that require a specific calibrated fit.
