Proto J5412N Hand Socket 3/8 Inch 12-point 1/2 Drive

Product Description

The PROTO J5412N is a 12-point hand socket designed for 3/8-inch fasteners and driven by a 1/2-inch drive. Built from chrome-plated steel, this standard-length socket delivers the durability expected in professional tooling. At 1-17/32 inches overall length and a compact width of 0.56 inches, it fits into tight spaces while maintaining solid fastener engagement. The 12-point configuration allows for 30-degree incremental repositioning, which is useful when working in confined areas with limited swing. Licensed tradespeople and service technicians across mechanical, HVAC, plumbing, and electrical disciplines will find this socket suitable for daily production use.

This socket is appropriate for residential and commercial service work where 3/8-inch fasteners are common. It performs in standard hand-tool applications including equipment removal, panel work, mechanical assembly, and fixture installation. The standard-length body suits most open-access fastener locations. It is packaged individually and sold as a single unit, making it a straightforward replacement or addition to an existing 1/2-inch drive socket set.

Installation Notes

Installed by any trade technician using 1/2-inch drive hand tools. Ensure the socket is fully seated on the fastener before applying torque to prevent rounding. Inspect the socket and drive tool for cracks or wear before use. This socket is not tether capable and should not be used in overhead applications where drop hazards exist without additional securing measures.
