SGK Mechanical Torque Gauge

The SGK Mechanical Torque Gauge

The SGK mechanical torque gauge operates in both directions of rotation (clockwise and counterclockwise), with graduations visible on the side and face of the instrument. They allow torque readings in both grip configurations.

Its three-jaw chuck with a knurled surface ensures a secure grip even on irregularly shaped or small-diameter workpieces. The face of the inserted ruler protects the scale from accidental damage.

The accuracy is ±3% of the displayed value over the entire measurement range. As an option, the SGK-G model includes a peak indicator that records the maximum value reached after release—please specify this when ordering.

Application of the mechanical torque gauge

The SGK mechanical torque gauge is used in all industries where very low torques need to be measured accurately :

Electronics and Electrical Engineering
Measurement of the starting torque of potentiometers, rotary encoders, switches, and adjustment knobs. The three-jaw chuck fits small shafts and buttons of various shapes without requiring a special adapter.

Cosmetics and Packaging
monitoring the torque required to open and close small caps, pen caps, or precision closure mechanisms on luxury bottles. The measurement range in mN·m covers the typical torques for these assemblies.

Watchmaking and Precision Engineering
checking the operating torque of watch mechanisms, ball joints, and precision joints, where excessive force could damage the parts.

Quality control in production
Verification of starting torque and operating torque on lightweight mechanical subassemblies, either at the start of the production line or during final inspection.

R&D and laboratories
characterization of the rotational behavior of precision mechanical components, validation of friction torques, repeatability studies on small mechanisms.

How to Use the SGK Mechanical Torque Gauge

The SGK gauge is easy to use and requires no special training. The component to be tested (button, shaft, cap) is clamped in the three-jaw chuck, ensuring that it is properly centered. The operator then turns the wrench in the tightening or loosening direction, as desired, and reads the torque value directly from the scale.

For applications requiring the measurement of maximum torque (starting torque, holding torque), the SGK-G model with a peak indicator is recommended. The indicator needle remains in position after the peak, allowing for easy reading without having to hold it in place.
The SGK gauge requires no power supply, software, or display. It is a measurement tool that is ready to use, portable, and suitable for use in any environment.
