Proto J4712LM Deep Hand Socket 12mm 6-point 1/4 Drive

Product Description

The PROTO J4712LM is a 6-point deep hand socket designed for 1/4 inch drive ratchets and breaker bars. Built around a 12 mm socket opening, the deep-length profile provides extra clearance to reach recessed fasteners, extended studs, and bolt protrusions that a standard-depth socket cannot access. The chrome-plated finish resists corrosion and makes cleanup straightforward after greasy or oily jobs. Measuring 2.8 inches in length, this socket fits standard 1/4 inch drive tool setups and is suited for use in automotive, HVAC, plumbing, and general mechanical service work.

This socket is appropriate for light-duty to medium-duty fastener work where a 12 mm hex fastener sits below a surface or on a threaded stud requiring additional socket depth. The 1/4 inch drive sizing makes it a natural fit for tight-access areas where a larger drive would be impractical. Technicians in HVAC, automotive, and plumbing trades commonly reach for this profile when working in confined equipment spaces or equipment panels where fastener clearance is limited.

Installation Notes

A licensed technician or trained mechanic should verify fastener size before use to prevent socket or fastener damage. Always ensure the socket is fully seated on the fastener before applying torque. Inspect the socket and drive square for cracks or wear before each use. Hand sockets are not rated for impact driver use unless specifically designated as impact-rated.
