Proto JRR10042 Socket Retaining Ring 1 in Drive

Product Description

The PROTO JRR10042 is a socket retaining ring designed for use with 1 inch drive hand tools and impact sockets. It seats in a 2-5/8 inch groove diameter and measures 2.835 inches in overall ring diameter with a height of 0.21 inches. This type of retaining ring locks a socket onto the drive square of a ratchet, breaker bar, or impact wrench, preventing unintentional socket release during use. It is a direct service and replacement component for professional mechanics, industrial maintenance technicians, and tool repair specialists working with heavy-duty 1 inch drive tooling.

Socket retaining rings are used wherever 1 inch drive sockets require a secure connection to the drive tool. Common applications include heavy equipment repair, truck fleet maintenance, industrial machinery service, and other high-torque applications where a 1 inch drive is standard. This ring is suited for shop environments and field service operations that maintain or rebuild socket sets and drive tools.
