1.product introduction
4.8 8.8 grade carbon steel hexagonal nut Purpose: Locking wire external joints or other pipe fittings.
The working principle of the nut is to self-lock using the friction between the nut and the bolt. However, the reliability of this self-locking will be reduced under dynamic loads. In some important occasions, we will take some anti-loosening measures to ensure the reliability of nut locking. The use of locking nuts is one of the anti-loosening measures.
