Proto J7342 Impact Socket 1/2 in Drive 1-5/16 in 12-point

Product Description

The PROTO J7342 is a 12-point impact socket designed for use with 1/2 inch drive impact wrenches and rattle guns. It accepts a 1-5/16 inch fastener and measures 3.5 inches in overall length, giving it the reach needed for recessed or deep-set hardware. Built for high-torque impact applications, this socket is intended for use by mechanics, millwrights, and industrial maintenance technicians who rely on tools that hold up under repeated impact stress. The 12-point configuration allows for multiple engagement positions around the fastener, which is useful when working in tight or awkward spaces.

This socket is suited for heavy equipment maintenance, fleet service, industrial assembly, and structural fastener work where a 1/2 inch drive impact tool is standard. The 1-5/16 inch size covers a range of common applications including suspension components, large fasteners on agricultural equipment, and construction hardware. It fits standard 1/2 inch square drive impact wrenches and can also be used with a torque wrench when controlled torque is required.

Installation Notes

Impact sockets should be used only with impact-rated drive tools. Never use standard chrome sockets with impact wrenches, as they are not rated for impact stress and can shatter. Ensure the socket is fully seated on the fastener before applying torque to avoid rounding. When using with a torque wrench for controlled tightening, follow the fastener manufacturer torque specifications.
