The difference between self-tapping screws and anti-loosening screws

The anti-loosening screw uses thermal spraying technology to divide the main body into a special engineering plastic of nylon and spray it on the screw thread. When the screw is tightened, this layer of engineering plastic will produce strong reaction and friction when it is tightened improperly. force, and then prevent the screw from retreating to prevent loosening.
Another kind of anti-loosening screw is dispensing screw, which is pre-coated with anti-loosening screw glue on the thread of the screw. Anti-loosening glue is a high-viscosity, non-toxic, touch-deformable, water-based pre-applied thread sealant, suitable for Yu active glue. After drying, the product becomes an elastic, strong adhesion, non-curing sealant, which can be used for sealing tapered or straight threads. After the screw coated with anti-loosening glue is screwed into the special body, it can be tightly attached to the surface of the product after the glue dries, thereby achieving the effect of anti-loosening.
Anti-loosening screw is a process carried out after screw production, so self-tapping screw can also become anti-loosening screw. We only need to coat the thread part of self-tapping screw with anti-loosening, anti-loosening glue, etc. to become anti-loosening screw.
