Why it's a great deal
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 shallow 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
