Proto J4716M Hand Socket 16 Mm 6-point 1/4 Drive

Product Description

The PROTO J4716M is a 16 mm, 6-point hand socket designed for use with a 1/4 inch drive ratchet or handle. Built from alloy steel with a chrome plating finish, this standard-length socket measures 0.875 inches in overall length and delivers a secure, corner-drive grip on hex fasteners. The 6-point geometry reduces the risk of rounding fastener heads compared to 12-point designs, making it a reliable choice for precision fastening tasks. It meets ASME B107.5M standards and carries a limited lifetime warranty. Mechanics, maintenance technicians, and service pros will find this socket well-suited for tight, controlled torque applications.

This socket is intended for hand-tool use in automotive, industrial, and general mechanical service environments. The 1/4 inch drive size makes it appropriate for smaller fasteners where controlled torque and compact tool access are priorities. Standard length suits most open-access fastener locations. It is not tether capable, so it is best suited for ground-level or bench work where drop hazards are not a concern.

Installation Notes

Install and remove using a 1/4 inch drive ratchet, torque wrench, or T-handle. Ensure the socket is fully seated on the fastener before applying torque to avoid slippage or fastener damage. This socket is not tether capable and should not be used in elevated work environments where dropped-tool hazards are present. Inspect for cracks or wear before each use and replace if any deformation is observed.
