Proto J4716N 1/2 Inch 12-point Hand Socket 1/4 Drive

Product Description

The PROTO J4716N is a 1/2 inch, 12-point hand socket with a 1/4 inch drive, built for professional-grade fastener work in mechanical, maintenance, and trade applications. Constructed from steel with a chrome-plated finish, this standard-length socket measures 1-15/64 inches in overall length and weighs approximately 0.066 pounds. The 12-point design engages hex fasteners at multiple contact angles, giving technicians more positioning options in tight spaces. It meets ASME B107.110-2012, AS4984A, and SAE AS954G standards, confirming it is built to recognized dimensional and performance specifications. Licensed mechanics, HVAC technicians, and maintenance professionals reach for this socket for routine drive-tool work where a compact 1/4 inch drive setup is preferred.

This socket is suited for light- to medium-duty fastener removal and installation tasks across residential and commercial maintenance environments. The 1/4 inch drive size makes it compatible with standard 1/4 inch drive ratchets, extensions, and adapters. Its compact form is well-suited for underdash automotive work, control panel access, equipment maintenance, and other tasks where a smaller drive size provides better maneuverability. The chrome finish resists corrosion during normal service conditions. PROTO backs this socket with a lifetime warranty.
