When you tighten a bolt in a bolted joint, you use a twisting force, called torque. This tension actually causes the bolt to stretch a very small amount, like pulling on a spring. And like a stretched spring which tries to return to its relaxed state, the stretched bolt attempts to relieve the tension by returning to its original length. The result is a compression, or clamp force, which pulls the bolt head and the nut towards each other, clamping the joint together. To ensure the joint is secure, a certain amount of clamp force must be developed — too much may cause warping of the joint or a broken bolt, and too little may risk a loose, unsecured joint. But how does a field operator tightening the bolt determine when enough tension has been reached that will create the right amount of clamp force?
