Proto JRR37567 Socket Retaining Ring 3/8 Inch Drive

Product Description

The PROTO JRR37567 is a socket retaining ring designed for use with 3/8 inch drive sockets. It seats in a 0.67 inch groove diameter and measures 0.745 inches in ring diameter and 0.075 inches in height. The retaining ring secures sockets onto drive tools, preventing unintended disengagement during use. It is a small but critical fastening component used by mechanics, tool repair technicians, and trade professionals who maintain hand tool sets or replace worn retaining hardware on existing sockets and drive tools.

This retaining ring is suited for shop and field use wherever 3/8 inch drive tool maintenance is performed. Typical applications include replacing cracked or sprung retaining rings on ratchets, extensions, and impact-rated sockets. At 0.01 pounds, it is a lightweight individual replacement piece sold in a package quantity of one, making it appropriate for single-socket repair or low-volume restocking of tool maintenance supplies.

Installation Notes

Installation is typically performed by mechanics or tool technicians using snap ring pliers sized for internal or external retaining rings, depending on groove orientation. Ensure the groove is clean and free of debris before seating the new ring. Do not over-spread the ring during installation, as this can compromise its retaining force. Inspect the groove for wear or deformation before installing a replacement ring.
