Proto J5016B Deep Hand Socket 1/2 in 12-point 3/8 Drive

Product Description

The PROTO J5016B is a deep hand socket designed for professional-grade fastener work in tight or recessed locations. Built from alloy steel with a black oxide finish, this socket accepts a 3/8 inch drive and fits 1/2 inch fasteners. The 12-point design allows engagement from multiple angles, which is useful when working in confined spaces with limited swing arc. At 2-1/8 inches overall length, it provides the clearance depth needed for recessed bolts and studs. Licensed technicians across mechanical trades keep this socket in rotation for its durability and standard compliance with ASME B107.1.

The J5016B suits residential and commercial maintenance, mechanical assembly, and field service applications where deep-reach access is required. HVAC technicians, plumbers, and electricians use deep sockets when securing equipment panels, mounting hardware, or working around pipe fittings and conduit. The 3/8 inch drive size keeps the overall profile manageable for moderate-torque fastener work without stepping up to a bulkier 1/2 inch drive tool. This socket is sold individually and is appropriate for both shop and field use.

Installation Notes

This socket is installed by qualified mechanics and trade professionals working on fastener-intensive equipment. Always ensure the drive tool and socket are fully seated before applying torque to prevent rounding. Inspect the socket for cracks or deformation before each use. Follow applicable OSHA hand tool safety guidelines when using in overhead or confined-space environments.
