During manual screwing the wrists and muscles are subject to a lot of stress. This is helped by the especially ergonomically shaped SoftFinish screwdriver, which ensures optimum transmission of manual force. With the long, slim grip sizes, small screws can be tightened safely and quickly. For screwing in larger screws there are large handle sizes that can be used to apply higher torques. Moreover, the different grip sizes are adjusted to the equal size of the hand by screwdriver professionals. The roll protection and the screw symbol printed on the handle ensure efficient work. The protective insulation was integrated in the blade in Wiha slimTECHNOLOGY, specially designed for electrical applications, in order to enable up to 33% slimmer blades. Even deep-lying screw and spring elements can be achieved with ease. The insulated screwdrivers are subjected to a routine test according to the international standard IEC 60900 and enable a safe working in the area of conducting parts up to 1,000 V AC.
