anti loose screw thread locked screws

The fastener pre coating technology widely used in screw anti loosening treatment is the first successfully developed by the United States and Germany in the world. One of them is to use special technology to permanently adhere special engineering resin to the screw teeth. By utilizing the rebound properties of engineering resin materials, bolts and nuts can achieve absolute resistance to vibration and impact through compression during the locking process, completely solving the problem of screw loosening. Nailuo is a registered trademark used by Taiwan Nailuo Company on screw anti loosening treatment products, and screws that have undergone Nailuo Company's anti loosening treatment are named Nailuo Screws on the market.

There are many types of anti loosening treatments for screws on the market, one of which uses engineering resin, usually with two coating angles of 360 degrees and 180 degrees along the circumference of the screw tooth diameter.

The anti loosening treatment of screws can be divided into two main streams based on the materials used;

One method is to use special engineering plastics and special processing processes to attach the engineering plastics to the surface of the screw teeth, causing the engineering plastics to be squeezed during the locking process to generate a strong reaction force, increasing the friction between the screw teeth and providing absolute resistance to vibration, completely solving the problem of screw loosening.

Another anti loosening treatment is to pre coat special chemical adhesive onto the screws. This chemical adhesive is a high viscosity, non-toxic, and can be pre applied to threads due to contact deformation, making it suitable for automatic gluing. After drying, the adhesive will form a solid coating on the surface of the screw. This coating will undergo chemical changes as the screws lock into the nuts, which can tightly bond the screws and nuts together to prevent loosening and detachment.

The anti loosening treatment on the thread surface greatly enhances the anti loosening characteristics of the screw. Commonly used on devices or supplies that vibrate or move, such as cars and mobile precision electronic products, such as laptops, mobile phones, etc.
