Proto J7318 Impact Socket 1/2 in Drive 9/16 in 12-pt

Product Description

The PROTO J7318 is a 12-point impact socket designed for heavy-duty fastener work in professional trade and industrial environments. Built for use with a 1/2 inch drive impact wrench or breaker bar, it accepts a 9/16 inch fastener and measures 3.25 inches in overall length. The 12-point geometry allows engagement in tighter spaces where swing arc is limited. At 0.4 pounds, it is compact enough for repetitive use without adding unnecessary weight to a tool setup. This socket is suited for mechanical, HVAC equipment assembly, electrical panel work, and general maintenance tasks where impact-rated tooling is required.

The J7318 is intended for use in professional shop and field environments. It fits standard 1/2 inch drive impact tools including pneumatic, electric, and cordless impact wrenches. Its 3.25 inch overall length provides enough reach for recessed fasteners without excessive extension. Typical applications include equipment mounting, ductwork and electrical enclosure assembly, pump and motor installation, and general mechanical service work across HVAC, plumbing, and industrial maintenance trades.

Installation Notes

Install and remove this socket only with impact-rated drive tools. Do not use impact sockets with standard chrome ratchets not rated for impact use, as this can cause tool failure. Always verify the fastener size matches the socket before applying torque. Inspect the socket for cracks or deformation before each use and remove from service if damage is found.
