What do you mean, anti-loosening screws?

Anti-loosening screws are hot spraying skills will be the main component of nylon special Engineering plastics sprayed on the threaded teeth, when the thread in the tightening process, this layer of engineering plastics are kneading and the occurrence of strong reaction force and friction, and then hinder the screw retreat, to reach the role of anti-loosening. Another anti-loosening screws are dispensing screws, is through anti-loosening screw glue, anti-loosening screws pre-coated glue, anti-loosening glue, is a high viscosity, non-toxic, touch deformation, water-based pre-coated thread sealant, suitable for active glue coating. After boring, the product becomes a kind of elasticity, strong adhesion, no need to solidify the sealant, can be used for conical or straight thread sealing.
