Two Size Markings
The size is marked in two ways on every socket—both as a high-visibility laser marking and a permanent stamped marking.
Full-Length Socket Well
While the overall socket is a standard length, the interior well extends fully into the socket, which allows better fastener engagement in more situations.
Drive Tool Retention
Sockets work for both types of anvils found on 1/2 inch drive impact wrenches:
Friction Ring Anvil | Detent Pin Anvil |

Prevents Fastener Round-Off
Prevents Fastener Round-Off
Radiused corners prevent fastener round-off by applying force to a fastener’s flat sides, rather than its corners.
Sockets Exceed ANSI Torque Standards
Each socket size meets a minimum of 1.3 times the ANSI/ASME standard for proof torque.
(A single-cycle test applies torque until a specified value is reached without failure or permanent deformation.)
