SNAP-ON INDUSTRIAL BRANDS 30406-TH SOCKET DEEP 12PT-TH 1/4DR 3/16IN

High-polished socket cleans easily - Williams T@H sockets, extensions, and adaptors feature a locking hole on all four sides, not just one. Williams T@H ratchets and drive tools feature a locking pin which mates with the side lock hole for positive retention. This reduces the risk of misaligning the socket that typical competitor’s sockets with just one side hole create.
