Details

The front of the socket has a laser marking, the back has a stamped marking.

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

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 1/2 inch drive impact wrenches:
Graphic showing green check marks on friction ring anvil and detent pin anvil
Graphic showing how the force applied by a socket to a fastener is on the flat sides of the socket and not the corners, preventing 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.
