Fastening torque
Bolts and screws secure many constructions, and the equal integrity and performance of each is crucial.
They are often secured to a specified torque or number of rotations, such that a residual torque prevents loosening, but is not so much as to cause future strain failure in the component.
Fasteners can be tested for their tensile strength, but under a full test rotation a ‘process signature’ can be obtained using a programmable torque tester.
This will detect any variations in torque that indicate departure from specification such as misthreading.
