Designed by SCA, this Angular Torque Gauge (1/2 drive) is a tool used to measure the force applied to a fastener while tightening. It also ensures that each component has an equal amount of tightness and is equipped with an easy-to-read display. How easy is it to use? Use of this gauge is not challenging, and begins by placing the gauge over the bolt and tightening it using a wrench. When the product's suggested degree is met on the meter, you stop tightening and remove your wrench.
