摘要：
When a gradient of fastening torque for a bolt decreases by a certain amount from its maximum value, the bolt is further turned by a specific angle and the true or false of its yield point is detected based on the variations of torque, or torque gradient before and after this further bolt turning so that bolt fastening will be terminated only when true yield point has been detected.
