To select the correct PROTO impact socket, match the drive size (e.g., 1-1/2") to your impact wrench, and the socket size (e.g., 3-1/2") to the fastener. Use 6-point sockets for maximum torque transfer and reduced rounding. The Black Oxide finish suits general industrial use. Always verify SAE or metric sizing for your application.
