Proto JRR50130 Socket Retaining Ring 1/2 Inch Drive

Product Description

The PROTO JRR50130 is a socket retaining ring designed for use with 1/2 inch drive sockets. This small but critical component keeps sockets securely locked onto the drive square of a ratchet, breaker bar, or impact tool during operation. The ring seats into a 1.3 inch groove diameter, with an outer ring diameter of 1.43 inches and a height of 0.13 inches. It is a direct replacement part for worn or lost retaining rings on 1/2 inch drive tools. Mechanics, technicians, and tradespeople who maintain their own tool inventory will find this a straightforward service item.

This retaining ring is suited for any professional shop environment where 1/2 inch drive sockets are in regular use. Applications include automotive repair, industrial maintenance, HVAC mechanical service, plumbing rough-in, and general trade work. When a socket shows signs of slipping or the original ring becomes deformed or missing, this replacement restores the secure fit between socket and drive tool without the need to replace the socket or the drive tool itself.

Installation Notes

Installation is typically performed by hand or with a small pick tool to seat the ring into the groove on the drive square. Ensure the drive square and groove are clean and free of debris before installing the new ring. No special certifications are required, but always verify the ring is fully seated before applying load to the socket.
