Proto JRR37595 Socket Retaining Ring 3/8 in Drive

Product Description

The PROTO JRR37595 is a socket retaining ring designed to secure sockets onto 3/8 inch drive tool shanks. It seats in a groove with a 0.95 inch groove diameter, features a ring diameter of 1.025 inches, and sits 0.075 inches high. This small but critical component prevents sockets from slipping off the drive during use, keeping the tool assembly together under the repetitive stress of production and service work. It is installed by mechanics, automotive technicians, and general trade professionals who maintain or rebuild 3/8 inch drive socket sets.

This retaining ring is suited for use with 3/8 inch drive socket sets in automotive, industrial, and general maintenance applications. It is a direct replacement component for worn or lost retaining rings on existing 3/8 inch drive tools. Typical install scenarios include socket set rebuilds, tool refurbishment, and fleet maintenance shops where individual socket drive components are serviced rather than replaced as a complete assembly.

Installation Notes

Installation is typically performed by hand or with snap ring pliers rated for external retaining rings. Ensure the groove on the drive shank is clean and free of debris before seating the ring. Confirm the ring is fully seated in the groove before applying load to the socket assembly. No power tools or special certifications are required for this replacement.
