"WERA 004557 8790 HMC DEEP SOCKET WITH 1/2"" DRIVE 17 X 83 MM ZYKLOP"

Long 1/2" sockets for manual and machine use (ISO 2725-part 3) with ball-retention groove; for hexagon screws and nuts. For manual and machine use (without impact) and deep access or fastening on studs. Take it easy colour coding for easy finding of the right tool. Knurling enables effective use even with greasy hands. The six-point profile enables the transmission of high forces and places less strain on the flats of the nut or screw head than a twelve-point profile. Thanks to their limited return angle, fine-tooth ratchets make a twelve-point profile unnecessary, even in confined spaces.
