  • What is the effect of heat treatment on improving the fatigue strength of bolts?

    The fatigue strength of bolts has always been an issue of concern. Data show that most of the failure of bolts is caused by fatigue damage, and there is almost no sign of fatigue damage, so major accidents can easily occur when fatigue damage occurs. Heat treatment can optimize the performance of fastener materials and improve their fatigue strength. In view of the increasingly high use requirements of high-strength bolts, it is even more important to improve the fatigue strength of bolt materials through heat treatment.

  • What is the working principle of the locking nut?

    Nut principle: The working principle of the nut is to use the friction between the nut and the bolt for self-locking. However, the reliability of this self-locking will be reduced under dynamic load. In some important occasions, we will take some anti-loosening measures to ensure the reliability of the nut locking. Among them, the use of locking nuts is one of the anti-loosening measures.
