Technician A says that a nonhardened nut loses clamping ability each time it is retorqued. Technician B says that a high-grade capscrew loses clamping ability each time it is retorqued to specification. Who is right?

Question

Quizplus · Accepted Answer

Technician A is correct. Nonhardened nuts can lose their clamping ability each time they are retorqued due to stretching and deformation of the threads. On the other hand, Technician B is incorrect. High-grade capscrews, especially those made of alloy steel, can be retorqued several times without losing clamping ability if done to the proper specifications.
