Bolt, one of the most widely used fasteners in the industry, is usually tightened by applying torque to the head and/or nut. As the bolt is tightened, it is stretched (preloaded). Preload tension is necessary to keep the bolt tight, increase join strength, create friction between parts, and improve fatigue resistance.

In this application, FUTEK''s TRH Hex-Drive Rotary Torque Sensor has been coupled to a power tool to verify its torque and rotational angle as it fastens a bolt into a fixed plate. These measurements can be read on either FUTEK''s digital displays, the IHH500 or IPM650, or streamed directly to a PC using FUTEK''s USB520.
