Proto J4710S Hand Socket 5/16 in 8-point 1/4 in Drive

Product Description

The PROTO J4710S is a 5/16 inch, 8-point hand socket designed for professional hand-tool use in mechanical, HVAC, plumbing, and electrical service applications. Built from alloy steel with a chrome-plated finish, this standard-length socket measures 7/8 inch in overall length and accepts a 1/4 inch drive. The 8-point configuration is specifically suited for 12-point and square-head fasteners where controlled engagement is required. This socket meets AS4984A and ASME B107.110-2012 standards, confirming dimensional and performance compliance for professional trades work. It is not tether capable, making it appropriate for standard service environments where tool-tethering requirements are not in effect.

This socket is used across a wide range of trade service scenarios including HVAC equipment servicing, electrical panel and fixture work, plumbing fixture installation, and general mechanical assembly. The 1/4 inch drive size targets confined-space and low-torque fastener applications where a smaller drive profile is necessary. Standard length suits the majority of open-access fastener situations without extended reach requirements. It is a single-piece, per-package item suited for individual addition to a professional socket set or service kit.

Installation Notes

This socket is installed and used by licensed HVAC technicians, electricians, plumbers, and mechanical service professionals. Verify the fastener head configuration before use to confirm the 8-point socket properly engages the fastener. Use only with 1/4 inch drive tools rated for the intended torque range. Inspect the socket for cracks or wear before each use and remove from service if any deformation is observed.
