Web17 dec. 2024 · The threads of the nut work with the threads of the screw to apply force to either side of the fastened material. This tension is called Bolt Preload, which is the compression created as the nut is tightened against the bolt (or vice-versa). When a load (weight) is placed on a bolt, it is limited to the amount of load the bolt can handle before ... http://www.chapmanssfs.com/torque-tightening-values-structural-steel-bolts/
WebT = K×F×D where T is the torque measurement, K is the nut factor, F is the tension and D is the bolt diameter. With this equation, if you know K, F and D, you can multiply them to get the torque needed to tighten the bolt so that it has the right amount of tension.
