Proto J4712LT Deep Hand Socket 3/8 in 12-point 1/4 in Drive

Product Description

The PROTO J4712LT is a 12-point deep hand socket designed for 1/4 inch drive ratchets and extensions. Built from alloy steel with a chrome finish, it accepts 3/8 inch fasteners and provides the added depth needed to reach recessed or stud-mounted hardware. At 2 inches overall length, it offers clearance where standard-depth sockets fall short. This socket is sized for hand tool use and is a staple in the kits of HVAC technicians, plumbers, electricians, and general trade mechanics who regularly work in confined or recessed spaces.

The J4712LT fits residential and light commercial service applications where 3/8 inch fasteners are common on panels, access covers, equipment housings, and mechanical assemblies. The 12-point geometry engages fastener flats at multiple contact positions, making it easier to work in tight swing arcs. Its deep length suits applications where bolt shanks, threaded studs, or stacked components prevent a standard socket from seating fully.

Installation Notes

This socket is intended for hand tool use by qualified trade professionals. Always confirm the fastener drive size and point count match before applying torque. De-energize or isolate any equipment before removing fasteners on electrical panels or mechanical enclosures. Do not use hand sockets with impact drivers unless the socket is rated for impact use.
