- Retaining rings are used to help secure sockets onto drive tools
- They are not intended to bear any load
- The rotational forces are between the drive tool and the socket
- The resin crush gauge on the pin helps indicate when a socket is excessively worn and should be replaced
- Drive tool and socket should line up when in use and should not pinch the crush gauge
- Cracked sockets and/or worn drive tools cause each other to turn excessively in relation to each other
- This action pin the small fin or the crush gauge on these retaining rings
- If the crush gauge is pinched, it is an indication that the socket and or the drive tool need to be replaced
- One-piece construction, no loose parts
- Pin is made of resin which allows the material to compress without breaking
- Part numbers are embossed on the rings near the point at which the pin and ring meet
