Anti-loose screws can be divided into two categories from the production point of view
Use special engineering plastics and special processing to attach engineering plastics to the screw tooth surface
the first sort:
Use special engineering plastics and special processing to attach engineering plastics to the screw tooth surface,
During the locking process of the screw, the engineering plastic is squeezed to produce a strong reaction force,
Increasing the friction between the screw teeth provides absolute resistance to vibration and completely solves the problem of screw loosening.
Anti-loosening screw treatment is to pre-coat the screw with a special chemical adhesive.
The chemical adhesive is a high-viscosity, non-toxic sealant that can be pre-applied to threads with touch deformation, and is suitable for self-applied screws.
After drying, the glue forms a solid coating on the screw surface.
This coating will produce chemical changes after the screw is locked into the nut, which can tightly adhere the screw and nut together to prevent the screw from loosening and falling off.
