Torque tightening test is done to check the bolt torque tightening and rotational capacity of bolts by using various calibrated standard ranges of torqueing sensors and fasteners for measuring torque values. Measuring torque is essential for companies to ensure their product’s quality, safety and reliability isn’t compromised. Insufficient torque can cause a screw or bolt to loosen from vibrations. Excessive torque can cause fasteners to overstretch and break.
