The use of threads made by forming is being expanded mainly through the automotive and aerospace industries. The quality of the thread (profile, bearing depth - and so thus load-bearing capacity, roughness) is significantly influenced by the quality of the workpiece (ductility), the method of cooling and, above all, the diameter of the pre-drilled hole. If it is small, often the thread cannot be made and the tool is destroyed; if it is big, the thread does not have sufficient load capacity. Measurement of torque and axial force can be the first signal of non-destructive evaluation of thread quality. The cut method reveals profile-shaped details.
