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.

Full-Length Socket Well

The interior well extends far into the socket, which allows for better fastener engagement in more situations.

Drive Tool Retention

Each socket works with both types of anvils found on 1/4 inch drive impact wrenches:

Prevents Fastener Round-Off

Radiused corners prevent fastener round-off by applying force to a fastener's flat sides, rather than its corners.
