Proto J4775TA 1/2 Inch 12-point Hand Socket 1/4 Drive

Product Description

The PROTO J4775TA is a 1/2 inch, 12-point hand socket designed for professional fastener work across HVAC, plumbing, electrical, and general mechanical applications. Built from alloy steel with a chrome-plated finish, this socket accepts a 1/4 inch drive and delivers the access and grip needed for hex-head fasteners in tight or standard service environments. The 12-point configuration allows engagement at 30-degree increments, giving technicians more ratchet-swing flexibility in confined spaces. At 0.05 pounds, it is a lightweight addition to any trade socket set. It meets ANSI B107.1 standards for hand socket tools.

This socket is suited for residential and light commercial service work where a 1/4 inch drive tool is appropriate for smaller fastener sizes. Common install scenarios include electrical panel work, equipment access covers, fan assemblies, and control enclosures where 1/2 inch fasteners appear. The universal and flex-compatible socket type designation indicates it is designed to work with standard and universal-joint drive configurations, making it practical for off-angle fastener access during equipment service.

Compatibility

Designed for use with standard 1/4 inch drive ratchets, extensions, and universal joints. Compatible with the universal and flex drive configuration as noted in product specifications.

Installation Notes

This socket is installed by trade technicians and general mechanics using 1/4 inch drive ratchet sets. Always power down or de-energize equipment before accessing fasteners on electrical or HVAC components. Confirm fastener size before applying torque to avoid rounding. Inspect the socket for cracks or wear before each use and replace if the drive or socket bore shows signs of deformation.
