Proto J5222N 11/16 Inch 3/8 Drive 12-point Hand Socket

Product Description

The PROTO J5222N is a standard-length intermediate hand socket designed for 3/8-inch drive ratchets and breaker bars. Built from polished steel, this 11/16-inch, 12-point socket delivers consistent torque transfer on hex fasteners in tight service environments. It measures 1.73 inches in overall length and weighs 0.186 pounds, making it a solid everyday socket for bench work and field use. The 12-point configuration allows engagement at 30-degree increments, reducing the swing arc needed in confined spaces. Licensed HVAC technicians, plumbers, electricians, and mechanical service professionals keep sockets like this in rotation for equipment access panels, motor mounts, and fastener-heavy service calls.

This socket is suited for professional trade use wherever a 3/8-inch drive, 11/16-inch fastener is encountered. Common applications include HVAC equipment service, electrical panel and motor assembly work, plumbing fixture installation, and general mechanical maintenance. Its standard length fits most standard-depth fastener heads without the clearance issues associated with deep sockets. The polished finish resists surface corrosion during typical shop and field conditions.

Installation Notes

This socket is installed and used by any licensed trade professional working with 3/8-inch drive hand tools. Ensure the socket is fully seated on the drive before applying torque to prevent rounding of the fastener or damage to the tool. Inspect the socket for cracks or deformation before each use, and replace if any wear is detected. This socket is not rated for impact driver use.
