Wera Hex Key, T Shape

Wera

The Wera 400 i VDE Insulated 5mm Hex Plus Torque Indicator Screwdriver is a fixed-torque VDE screwdriver designed for safe, accurate tightening of hexagon socket screws in live electrical environments up to 1,000V AC. Individually tested to IEC 60900 at 10,000V, this tool is an essential piece of kit for electricians and electrical contractors working on live or potentially live installations. The tamper-proof design ensures the pre-set torque value cannot be accidentally altered, giving you full confidence that connections are tightened to the correct specification every time. The robust slip clutch delivers a clearly audible and tactile signal the moment the set torque is reached, immediately preventing over-tightening. This makes it ideal for critical electrical connections where precise torque control is non-negotiable. Importantly, the loosening torque is set significantly higher than the tightening torque, so no additional tools are required to undo connections. The T-handle design fills the hand naturally, with softly rounded recessed grips that allow comfortable, controlled operation during extended use. This ergonomic form ensures optimal power transfer whether tightening or loosening.
