The Wera Tools Zyklop sockets with 1/2" drive, No. 8790 HMC HF, feature a holding function designed to hold screws securely on the tool, especially in confined spaces where using a second hand to secure the screw is not an option. The Zyklop sockets and bit sockets are color-coded according to size as part of the Wera "Take it easy" Tool Finder system. The sockets are chrome vanadium steel and equipped with ball stop groove, knurling at the lower end for improved grip. The manual and machine sockets can be used for both hand and non-impact power tool applications.
