Proto J4720A Hand Socket 5/8 in 1/4 Drive 6-point

Product Description

The PROTO J4720A is a 6-point hand socket designed for precise fastener engagement in professional mechanical and maintenance applications. Built to a 5/8 inch socket size with a 1/4 inch drive, this standard-length socket measures 0.875 inches overall length and is constructed from alloy steel with a chrome-plated finish. The 6-point geometry reduces fastener rounding compared to 12-point designs, making it a reliable choice for technicians working on equipment where fastener condition matters. It meets ASME B107.1 standards and carries a limited lifetime warranty.

This socket is suited for light-duty to medium-duty hand tool use across trades including HVAC, plumbing, electrical, and general mechanical service. The 1/4 inch drive size makes it well matched for confined spaces and low-torque applications where a smaller drive is practical. Standard length fits the majority of typical service scenarios without the reach of an extension. It is packaged individually and sold as a single unit.

Installation Notes

This socket is installed by hand tool technicians across a wide range of trades. Ensure the drive connection is fully seated on the ratchet or wrench before applying torque. Inspect the socket and drive tool for wear or damage before use. Do not use hand sockets with impact drivers unless the socket is impact-rated.
