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 standard length, the interior well extends fully into the socket, which allows for better fastener engagement in more situations Drive Tool Retention - Sockets work with through-hole, friction ring, and detent pin anvils Prevents Fastener Round-Off - Radiused corners prevent fastener round-off by applying force to a fastener's flat sides, rather than its corners Materials and Finish - All of our 3/4 inch drive sockets, extensions, adapters, and reducers are made out of 4140 steel and have a corrosion-resistant manganese phosphate coating
