Wera's Zyklop 8790 B VDE wrenches are 3/8" VDE nuts with enhanced safety. Thanks to the yellow insulation core, which becomes visible in case of possible damage to the outer red VDE insulation layer, damaged insulated inserts can be detected immediately. The Zyklop 8790 B VDE socket wrench insert is a tool tested piece-by-piece according to IEC 60900 at 10,000 volts. It is approved for safe operation at a voltage of 1,000 volts.
