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 ... WebDetermining the proper torque for a fastener is the biggest problem in fastener installation. Some of the many variables causing problems are. The coefficient of friction between mating threads. The coefficient of friction between the bolthead (or nut) and its mating surface. The effect of bolt coatings and lubricants on the friction coefficients.
