The Wera VDE socket wrenches feature a multi-component Kraftform design for fast and fatigue-free working. The hard grip zones allow for high working speeds, while the soft zones ensure high torque transfer. Each wrench is individually tested at 10,000 volts to guarantee safe operation at the permissible voltage of 1,000 volts. The hexagonal anti-roll feature prevents the wrenches from rolling away at the workplace.
