Wera 400 Hex-Plus pre-Set Torque Indicator, Hex-Plus 4x60, 4Nm, 05005080001

The Wera 400 4mm Hex Plus Torque Indicator Screwdriver is a fixed-torque screwdriver designed for precise, controlled fastening using hexagon sockets. Built around a robust slip clutch mechanism, this torque indicator delivers a clearly audible and tactile signal the moment the set torque value is reached. Once triggered, the clutch prevents any additional torque from being applied, effectively eliminating the risk of over-tightening. A key practical advantage is the significantly higher loosening torque compared to the set tightening torque, meaning no secondary tools are required to undo fastenings. The tamper-proof design ensures the pre-set torque value cannot be accidentally altered during use - essential in professional environments where consistent torque application is critical. The T-handle is ergonomically shaped to fill the hand naturally, with softly rounded recessed grips that seat the fingers comfortably for extended periods. This design maximises power transmission while
