These wrenches need as little as 5° of sweep to move a fastener where a standard fixed torx wrench needs 60° or 12 times as much room. The thin head and shank design allows the wrench into spaces a ratchet and socket will not go. Meets ANSI, DIN and federal torque specifications for standard professional combination wrenches. Fully hardened, all metal construction with a mirror finish. Also in a set. E14 x E18
