Proto J5412MN Hand Socket 12mm 12-point 1/2 Drive

Product Description

The PROTO J5412MN is a 12 mm, 12-point hand socket designed for use with a 1/2 inch drive ratchet or breaker bar. Built from steel with a chrome-plated finish, this standard-length socket measures 1-17/32 inches overall. The 12-point geometry allows engagement from multiple positions, reducing the need to reposition the drive tool in tight work areas. It meets AS4984A, ASME B107.110-2012, and SAE AS955 standards. Technicians in HVAC, plumbing, electrical, and general mechanical trades reach for this socket when removing or installing metric fasteners on equipment, panels, and mechanical assemblies.

This socket is suited for both shop and field use wherever a 1/2 inch drive and a 12 mm fastener intersect. Common applications include equipment mounting hardware, panel fasteners, and mechanical component installation on residential and commercial systems. Its standard length fits the majority of accessible fastener locations without requiring an extension. The chrome finish resists corrosion during everyday use in varied service environments.

Installation Notes

Ensure the drive tool and socket are fully engaged before applying torque to avoid rounding fasteners or damaging the socket. Power down or de-energize any equipment before accessing fasteners on electrical panels or mechanical enclosures. This socket is not rated for impact driver use; use impact-rated sockets with pneumatic or electric impact tools. Inspect the socket for cracks or wear before each use and remove from service if damage is found.
