WebDo nuts or bolts fail first? The bolt fails in simple tension, while the nut fails when the resolved forces on the threads cause the nut to grow larger until the tips of the threads strip. With the difference in mechanisms, a nut made from an identical material is inherently much stronger than the bolt. WebFor one example, the bolt itself is tested for strength by the manufacturer by screwing the bolt into a standard testing fixture and subjecting it to pure tension. However, in typical applications, bolt tension is induced by torque on the nut and the bolt is subject to combined tension and torque, which may cause the bolt to fail at a load less ... eagle shirts men
