Proto J5208B 1/4 Inch 12-point Hand Socket 3/8 Drive

Product Description

The PROTO J5208B is a 1/4 inch, 12-point hand socket designed for professional fastener work in mechanical, industrial, and maintenance applications. Built from alloy steel with a black oxide finish, this socket provides corrosion resistance and durability under regular shop use. The 3/8 inch drive fits standard ratchets and extensions commonly found in trade toolkits. At 1-3/32 inches overall length, it sits in the standard-length category, giving technicians direct access to fasteners without added bulk. This socket meets ASME B107.1 standards, confirming it is manufactured to recognized dimensional and performance criteria for hand tools.

The J5208B is suited for use across a wide range of trade applications including HVAC service, plumbing rough-in, electrical work, and general mechanical maintenance. It is appropriate for both residential and light commercial service environments where a 3/8 inch drive tool set is in use. The 12-point geometry allows engagement from multiple positions, which is useful in confined or awkward fastener locations common in mechanical system installs and service calls.

Installation Notes

This socket is installed and used by any trade professional working with standard fasteners. Ensure the socket is fully seated on the fastener before applying torque to prevent rounding. Inspect the socket for cracks or wear before use, particularly in high-cycle service environments. Not tether capable — secure the tool appropriately when working at elevation or in confined spaces where drops are a hazard.
