WebCalculating Assembly Torque per ISO 68 & ISO 724. Combined Thread and Body Bolt Elongation Under Preload Formula and Calculator With torque or turn on a bolt thread, we’re trying to control the tightening process through the forces applied to, or the motion of, the nut. Screw Stress Area 100 ksi & Greater. Bolt Stress Area less Than 100 ksi. WebThis tensile force in the bolt creates a compressive force in the bolted joint known as clamp force. For practical purposes, the clamp force in an unloaded bolted joint is assumed to be equal and opposite of the preload. 1 If proper preload, and thus clamp force, is not developed or maintained, the likelihood of a variety of problems such as ...
