TEKTON 1/2 Inch Drive x 10 mm Deep 12-Point Impact Socket | SID23310

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 - 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 Works with Friction Ring or Detent Pin Anvils - Smooth walls inside the drive end and a detent pin hole make the sockets compatible with both drive tool anvil types Prevents Fastener Round-Off - Radiused corners prevent fastener round-off by applying force to a fastener's flat sides, rather than its corners High-Performing Steel Alloys - This socket is made from 50BV30 Chromium-Vanadium (Cr-V) and has a corrosion-resistant manganese phosphate coating
