1. Strengthen connection strength and improve connection conditions.
The low strength materials, such as aluminum and magnesium, can avoid the phenomenon of sliding wire and staggering teeth, and obtain excellent connection performance.
2. Wear resistance.
It can be used for the parts that are often disassembled, which can greatly improve the service life of the thread.
3. Increase the stress surface.
It is used for parts requiring strength connection force but not increasing screw hole diameter.
