To select the correct OTC locknut socket, match the drive size to your ratchet or impact wrench (e.g., 3/4 in) and the socket size to the lock nut's hex width (e.g., 2 1/4 in). Choose a deep socket for recessed nuts and a 6-point design for maximum grip. Verify the socket is SAE-rated for your application.
