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 a 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.
