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 ... Webbunits and with the load applied this decreases to 1 unit of force. The bolt would not actually ‘feel’ any of the applied force until it exceeded the bolts clamp force. Figure 10 shows the condition when a load of 3 is applied. The joint will separate and the 3 units of weight acting down will be balanced by the 3 units of force in the spring.
