Proto J7346 Impact Socket 1/2 in Drive 1-7/16 in 12-pt

Product Description

The PROTO J7346 is a 12-point impact socket designed for heavy-duty fastener removal and installation in demanding trade applications. Built for 1/2 inch drive impact wrenches, it accepts a 1-7/16 inch fastener size and measures 3.5 inches in overall length. The 12-point configuration engages fasteners at multiple contact points, making it well suited for high-torque impact work where access and speed matter. Licensed mechanics, industrial maintenance technicians, and service professionals rely on sockets like the J7346 for repetitive, high-cycle fastener work on equipment, machinery, and structural assemblies.

This socket fits standard 1/2 inch drive impact wrenches and is appropriate for automotive, heavy equipment, HVAC equipment installation, and general mechanical service work. The 1-7/16 inch socket size covers common large fasteners found on flanges, structural bolts, and equipment mounting hardware. The 3.5 inch overall length provides clearance for recessed fastener locations without the need for an extension in many applications.

Installation Notes

This socket is installed and used by licensed mechanics, maintenance technicians, and trade professionals working with impact wrenches or manual ratchets. Always confirm the drive tool is powered down or depressurized before changing sockets. Use impact-rated sockets exclusively with pneumatic or electric impact wrenches — do not substitute standard chrome sockets in impact applications. Inspect the socket for cracks or deformation before each use.
