WebbWhen tightening a bolt or nut, the applied torque must overcome the thread friction, the friction under the bolt head or nut and the inclined plane of the thread, to obtain a bolt preload (see Fig. 1A). While untightening, provided that the assembly remains in the same condition, the applied torque only has to overcome frictional forces. Webbtightening force from the handle to the threaded element (boss or stud). In fact, the results of several laboratory tests, perfomed with a special instrument that simulates the most severe use conditions, have shown that e.g. ERX.78 adjustable handle can withstand without yielding more than 100,000 tightening cycles, under the action of a Webb17 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 ... paravel discount code
