Thread Stripping BOLTCALC

Thread stripping sometimes referred to as thread shearing is when the shear stress acting on the threads is such that the threads either shear completely so that the nut becomes detached or partially in which case the strength of the thread is severely impaired The program will determine the force to shear both the nut internal thread and the bolt external thread
