TEKTON Metric 3/8-in Drive 23mm 12-point Impact Socket Individual

Size is marked both with a high-visibility laser marking and a permanent stamped marking that won't wear off

Deep 12-point socket opening provides an exact fit for 12-point fasteners

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

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