Wera 400 5mm Hex Plus Torque Indicator Screwdriver

The Wera 400 5mm Hex Plus Torque Indicator Screwdriver is a fixed-torque screwdriver designed for precise, controlled tightening of hexagon socket fasteners. Built around a robust slip clutch mechanism, this torque screwdriver delivers a clearly audible and tactile signal the moment the pre-set torque value is reached. Once triggered, the clutch prevents any further torque being applied — making over-tightening impossible and protecting sensitive fixings from damage. A key advantage of this tool is that the loosening torque is significantly higher than the set tightening torque. This means fasteners can be removed without reaching for additional tools, streamlining workflows on site or in the workshop. The ergonomic T-handle is shaped to fill the hand naturally, with softly rounded recessed grips that keep fingers positioned correctly during use. This design supports optimal power transmission and reduces fatigue during repetitive tightening tasks. The blade is also particularly corrosion resistant, making this tool well suited to demanding environments. Fixed at 5.0 Nm and tamper-proof against accidental adjustment, this screwdriver is ideal for applications where a consistent, repeatable torque is critical — such as electrical panel work, automotive assembly, or precision engineering tasks. Features and Benefits: • T-handle design ideal for transferring controlled tightening torque and high loosening torque • Slip clutch provides audible and tactile signal at the set torque value — over-tightening is not possible • Tamper-proof against accidental adjustment of the set torque value • Higher loosening torque than tightening torque — no additional tools required for removal • Ergonomic recessed grip handle for comfortable, accurate use • Particularly corrosion resistant blade for use in demanding conditions Contents: 400 Hex Torque Indicator, 5 mm x 5.0 Nm Specifications: Tip Size: 5 mm Torque Setting: 5.0 Nm
