Proto J4712LTM Deep Hand Socket 12mm 12-point 1/4 Drive

Product Description

The PROTO J4712LTM is a deep hand socket designed for professional-grade hand tool use in mechanical, automotive, and industrial service applications. Built from alloy steel with a chrome-plated finish, this socket accepts a 1/4 inch drive and fits a 12 mm fastener. The 12-point configuration allows engagement at multiple angles, useful in confined spaces where swing arc is limited. The deep-length profile accommodates extended bolts, studs, and recessed fasteners that standard-length sockets cannot reach. It meets AS4984A and ASME B107.110-2012 standards, reflecting consistent dimensional tolerances and material requirements expected by trade professionals.

This socket is suited for light-duty fastener work in automotive, HVAC equipment panels, plumbing fixture installations, and general mechanical assembly. The 1/4 inch drive pairs with standard ratchets, extensions, and torque wrenches in that drive class. The deep profile makes it particularly useful when working on recessed hardware or threaded rod installations where a shallow socket would not seat fully. Mechanics, HVAC technicians, and service plumbers routinely carry this size for equipment access panels and motor mounting hardware.

Key Features

• 12 mm socket size fits metric fasteners common in HVAC, automotive, and mechanical assemblies
• 12-point design allows engagement at 30-degree increments for use in tight access areas
• Deep-length profile seats over extended studs and recessed bolt heads
• Alloy steel construction provides durability under hand-torque loads
• Chrome-plated finish resists corrosion and simplifies cleaning
• Meets AS4984A and ASME B107.110-2012 standards for dimensional and material compliance

Compatibility

Designed for use with 1/4 inch drive ratchets, extensions, and torque wrenches. Fits 12 mm hex fasteners in any application where a deep-length socket is required.

Installation Notes

This socket is installed and removed by hand with a compatible 1/4 inch drive ratchet or torque wrench. Ensure the socket is fully seated on the fastener before applying torque to prevent rounding. Do not use impact drivers with this hand socket. Inspect the socket for cracks or wear before each use, and retire it from service if deformation is observed.
