The screws on terminal blocks, meter boards, and DIN rails are usually hex heads, and that job wants a nutdriver with the same VDE discipline as the rest of an insulated kit. The Wera 190i is individually tested at 10,000 volts to IEC 60900, so it is approved for work on circuits up to 1,000 V. Its impact strength is tested at -40°C too, so the insulation stays dependable in cold shops, unheated vans, and winter service calls.
The Kraftform Plus handle behaves the way the VDE line always does: hard handle zones ride smoothly through the hand for fast spinning and rapid repositioning, while the soft grip zones transfer real torque without your palm fighting the tool. The yellow VDE handle with Take-it-easy profile and size stamping means the right size announces itself the moment you reach into a tray or pouch.
Nine metric sizes from 5.5mm to 13mm on a 125mm shaft cover the hex sizes actually found on electrical equipment. No oddballs, no duplicates, just the range a working electrician reaches for.
