400 i VDE Insulated 4mm Hex Plus Torque Indicator Screwdriver

The Wera 400 i VDE Insulated Torque Indicator Screwdriver is a professional-grade tool designed for precision fastening of hexagon socket screws in live electrical environments up to 1,000V. This VDE-certified screwdriver features a robust slip clutch mechanism that delivers a clearly audible and tactile click when the pre-set 5.0 Nm torque is reached, preventing over-tightening and eliminating guesswork. The tool is tamper-proof, ensuring the torque setting cannot be accidentally adjusted during use. Individually tested at 10,000V according to IEC 60900 standards, it provides electricians and electrical contractors with complete confidence when working on live installations. The T-handle design offers exceptional ergonomic benefits, filling the palm whilst allowing fingers to rest in softly rounded recessed grips for optimal power transfer. The loosening torque value significantly exceeds the tightening torque, meaning no additional tools are required to remove fasteners – a practical advantage when working in confined spaces or at height. Ideal for electrical installation work, control panel assembly, and maintenance tasks where precise torque application is critical, this hex screwdriver combines safety, accuracy and durability for demanding trade applications.

Features and Benefits:

• Insulated, individually tested VDE T-handle torque indicator for safe working up to 1,000V
• T-handle is ideal for transferring controlled tightening torque and high loosening torque
• Error-free screwdriving due to non-slip friction clutch and exact torque transmission
• Distinctly audible and noticeable excess-load signal when the pre-set torque is reached
• Tamper-proof against accidental changing of set torque value Contents: 400 i VDE Hex Insulated torque-indicator, 4 x 5.0 Nm
