Wiha Torquevario-S Torque Screwdriver 0.1-0.6Nm 10%Accuracy 2852

The Wiha TorqueVario®-S torque screwdriver delivers a clearly audible and tactile signal at the preset torque limit, preventing over-torquing on critical fasteners. Torque range: Multiple ranges available (0.04–5.0 Nm). Accuracy: ±6% (standard) or ±10% (entry models) (EN ISO 6789). Accepts 1/4" insert bits and Wiha 4 mm interchangeable blades (series 2859), making it adaptable across Phillips, Torx, Pozidriv, and hex drive profiles. Manufactured in Germany.

Where this tool is used

• Electronics and PCB assembly — torque control on M2–M5 fasteners prevents cracking of PCB material or stripping of brass inserts.
• Medical device and pharmaceutical equipment maintenance — audit-ready torque compliance on critical fasteners in validated manufacturing environments.
• Automotive and aerospace sub-assembly — specification torque on engine, suspension, and safety-critical fasteners where under/over-torque creates liability.

Key specifications

Selecting the right option

Select torque range to cover the majority of your fastener specifications — TorqueVario®-S ranges from 0.04 Nm (precision electronics) to 5 Nm (light mechanical). Variable models suit multi-spec work; TorqueFix® (fixed) suits single-spec production lines. For traceability, calibrate against a reference standard per EN ISO 6789 at scheduled intervals.
