400 4mm Hex Plus Torque Indicator Screwdriver

The Wera 400 4mm Hex Plus Torque Indicator Screwdriver is a precision torque tool designed for consistent and accurate tightening of hexagon socket screws. This fixed-torque screwdriver features a robust slip clutch mechanism that delivers both audible and tactile feedback when the preset 4.0 Nm torque value is reached, preventing over-tightening and ensuring error-free fastening. The tamper-proof design safeguards against accidental adjustment of the torque setting, making it ideal for quality-critical applications where consistent torque values are essential. The tool's intelligent engineering provides a significantly higher loosening torque compared to its tightening specification, eliminating the need for additional tools when removing fastened components. The ergonomic T-handle design maximises power transmission whilst maintaining precision control during operation. The handle profile fills the hand naturally, with softly rounded recessed grips that reduce operator fatigue during repetitive tasks. The corrosion-resistant blade ensures long-term durability in demanding workshop environments. This torque indicator screwdriver is particularly suitable for assembly work, maintenance tasks, and applications requiring verifiable torque specifications. The 4mm hex socket size makes it ideal for electronics assembly, instrumentation work, and precision engineering applications where consistent fastening torque is critical.
