Proto J4716T 1/2 Inch 12-point Hand Socket 1/4 Drive

Product Description

The PROTO J4716T is a 1/2-inch, 12-point hand socket with a 1/4-inch drive, built for professional hand-tool use in mechanical, HVAC, plumbing, and electrical service applications. The socket features a chrome-plated finish that resists corrosion and simplifies cleaning in shop environments. At standard length with compact dimensions of 0.6 x 0.6 x 1.1 inches, it fits comfortably in confined spaces where larger sockets cannot reach. Weighing only 0.05 pounds, it is lightweight for frequent use in hand-tightening and removal tasks. The 12-point profile engages fastener heads at more positions than a 6-point, making it well suited for working in tight access angles common in trade service work.

This socket is intended for use with 1/4-inch drive ratchets, extensions, and torque wrenches in residential and light commercial service environments. It is well suited for fastener sizes found in control panels, equipment covers, junction boxes, and mechanical assemblies. The 12-point geometry makes it practical for hex-headed fasteners and some damaged fastener heads that require frequent repositioning of the drive tool. Licensed trades including HVAC technicians, plumbers, and electricians will find this a standard addition to a 1/4-inch drive socket set.

Compatibility

Designed as a standard 1/4-inch drive hand socket for use with 1/4-inch drive ratchets, flex handles, extensions, and torque wrenches accepting 12-point sockets in that drive class.

Installation Notes

Install and remove using a 1/4-inch drive ratchet or torque wrench rated for the fastener application. Always ensure the socket is fully seated on the fastener head before applying torque to prevent rounding. Power down electrical equipment and shut off relevant systems before accessing fasteners on live assemblies. Do not use hand sockets with impact drivers unless the socket is rated for impact use.
