Details

Two Size Markings

TEKTON Impact Socket 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

TEKTON Impact Socket Well

While the overall socket is a standard length, the interior well extends fully into the socket, which allows for better fastener engagement in more situations.

Drive Tool Retention

Sockets work for both types of anvils found on 3/8 inch drive impact wrenches:

Impact Wrench Friction Ring

Friction Ring Anvil

 Impact Wrench Detent Pin

Detent Pin Anvil

Prevents Fastener Round-Off
TEKTON Impact Socket Radiused Corners
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.)
