Overview

Applications

Torque arms are used for assistance when operating hand held tools such as screwdrivers and nutrunners. The torque arms in the SMC series have a large working range, are easy to position and handle. They are designed for heavy duty operations over a long period of time. The torque arms makes assembly more stable and reduces wear on accessories like bits and taps. It is recommended to use the SMC series of torque arms together with a balancer.

The torque arms reduces the strain on the operators arm, wrist and shoulder by reducing vibration, torque and weight during repeated actions. Even small amounts of repeated actions can lead to repetitive strain injury.
