Details

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.

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.

Access + Versatility

TEKTON Deep Impact Socket Fully-Stepped Shoulders

Fully Stepped Shoulders

The narrowed socket diameter goes all the way down to the base of the socket on small deep-length sizes. This allows for better reach into tight recessed areas.

TEKTON Deep Impact Socket Well

Full-Length Socket Well

Not only is the socket a deep length, but the interior well also extends far 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

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 1.2 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.)
