Product Description

Sunmao Aerospace is a leading China self-locking nut manufacturer, supplier and exporter. Self-locking nuts are special nuts that have the function of self-locking and are often used in situations where loosening is required. Their characteristics are that the last thread is specially processed into a polygonal or flange shape. When the self-locking nut is tightened, it can bite the metal surface by itself, thereby increasing the friction and preventing the nut from loosening under vibration or impact.

Features and applications

①Self-locking function

The self-locking nut has a self-locking function, that is, through special design or surface treatment, the nut and the receiver can generate greater friction to avoid loosening. It can ensure that the fastener will not loosen under long-term vibration and impact, avoiding the safety hazards caused by the loosening of the fastener.

②Anti-shock function

The product can play a certain anti-shock effect during use. In the case of mechanical vibration or impact, due to its self-locking characteristics, it can effectively avoid loosening and falling off. This ability is very important for most mechanical equipment, especially in occasions with harsh vibration environments and high safety risks.

③High temperature resistance

Self-locking nuts have good tolerance in high temperature environments, and some materials can even cope with high temperature environments of several hundred degrees Celsius, which is very important in industries such as industrial production and aerospace.

④Easy to install

It is also easier to install than traditional nuts. Since it can lock itself, it does not require tools such as manual wrenches, saving time and labor.
