“How can we make bolts resilient to stronger loads?”

 

Bolts are used to keep to keep objects together using compressive forces. However, in order to work, they need to have some initial force applied to them. This Preload is usually a compressive force that allows the bolt to withstand a tensile force equal to the same magnitude. The higher the compressive load, the higher the tensile resilience. However, if the bolt preload is too much, then it can weaken the Proof Strength. Therefore, when making a Bolt Preload, we must take into account both factors.
