Williams ST-818-TH 8-Point Tools at Height 1/2 Standard Socket Drive, 9/16"

Super torque lobular openings for greater turning power without deforming the fastener. 8 point sockets are designed for quick engagement on 4 point fasteners. - Williams that sockets, extensions, and adaptors feature a locking hole on all four sides, not just one. Williams that 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.
