Proto J7328 Impact Socket 1/2 in Drive 7/8 in 12-point

Product Description

The PROTO J7328 is a 12-point impact socket designed for heavy-duty fastener work in industrial, mechanical, and trade service environments. Built for use with a 1/2 inch drive impact wrench or ratchet, it accepts 7/8 inch fasteners and measures 3.5 inches in overall length. The 12-point design engages hex fasteners at multiple contact points, allowing repositioning in tight spaces. Weighing 0.68 pounds, this socket is suited for professionals who need reliable torque transfer without socket deformation under impact loads. Typically installed by mechanics, millwrights, pipefitters, and HVAC technicians working with bolted assemblies.

The J7328 fits standard 1/2 inch drive impact wrenches and ratchets commonly used in mechanical rooms, equipment service bays, rooftop unit installations, and general industrial maintenance. The 7/8 inch size covers a common fastener dimension found on equipment flanges, structural connections, and pipe supports. Its 3.5 inch overall length provides clearance for recessed fasteners without sacrificing torque control.

Installation Notes

Installation and fastener work with impact sockets should be performed by a qualified mechanic or trade professional. Always confirm the drive tool is powered down or air supply is disconnected before changing sockets. Inspect the socket for cracks or deformation before each use and do not use impact sockets with standard hand-drive extensions not rated for impact loads.
