ITEM FEATURES:

• 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
• Designed with a resin crush gauge to help identify when to replace worn sockets
• 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 pinches 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
• 1-piece construction, no loose parts
• Pin is made of resin which allows the material to compress without breaking
• 2 in groove
