Click-Type Service Torque Wrench, 3/4'' square, 80–400 Nm

The Stahlwille Service 730NR 40 FK torque wrench is a click-type, professional-grade tool built for reliability in demanding environments. Its innovative QuickSelect adjuster allows rapid and accurate torque settings, while the dual stop signal gives both audible and tactile confirmation when the set torque is reached.

The internal measuring element is only active during use, eliminating the need to manually reset the tool to zero — a major time-saver in fast-paced service environments. The color-coded double scale (N·m/ft·lb or ft·lb/in·lb) provides quick, at-a-glance differentiation, ideal for technicians working across metric and imperial units.

Engineered to resist chemical exposure, the two-component ergonomic handle features softer green inserts that are resistant to oils, greases, fuels, brake fluids, and Skydrol. Post-click torque or reverse-force misuse doesn’t affect the mechanism — a major advantage in industrial use where over-torque or jammed fasteners are common.

This wrench is calibration-ready with Stahlwille’s perfectControl® 7794 or 7706 system, and includes ISO 6789-2:2017 certification with ±4% deviation. From size 65 and up, it’s supplied in a durable textile carry bag. Backed by a registered design, the 730N is a next-generation torque solution for professionals.
