How to select the correct PROTO socket size?

To select the correct PROTO socket, match the drive size (1/2 in) to your ratchet or torque wrench, and the socket size (9/16 in) to the fastener head. A 6-point deep socket provides better grip on hex bolts than a 12-point. Confirm SAE vs. metric before ordering.
