The Wera 400 i VDE Insulated 4mm Hex Plus Torque Indicator Screwdriver is a fixed-torque VDE screwdriver designed for safe, controlled tightening of hexagon socket screws in live electrical environments. Built to IEC 60900 standards and individually tested at 10,000V, this tool is approved for safe working at up to 1,000V — making it an essential piece of kit for electricians and other tradespeople working on or near live electrical installations. The robust slip clutch delivers a clearly audible and tactile signal the moment the pre-set torque is reached, preventing overtightening without any guesswork. Because the loosening torque is significantly higher than the tightening value, no additional tools are required to release screw connections — keeping your workflow efficient on site. The T-handle design fills the hand naturally, with softly rounded recessed grips that allow comfortable, ergonomic control during both tightening and loosening operations. The torque setting is tamper-proof, so there's no risk of accidental adjustment between uses.
