Key specifications

Selecting the right option

Select by drive size (1/4", 3/8", 1/2", 3/4", or 1") to match your ratchet or power tool, and by size in metric (mm) or AF (fractional inch) to match the fastener. Choose standard depth for general use or deep for fasteners on studs or in recesses. 6-point sockets provide better torque transfer on worn fasteners; 12-point allow more engagement positions.
