The nylok patch self-locking technology is the first in the United States to develop successfully in the world. It uses special technology to make special engineering resin permanently adhere to the screw thread, and uses the resilience of engineering resin materials to make bolts and nuts tighten during the locking process. The absolute resistance to vibration and impact is achieved through extrusion, which completely solves the problem of screw loosening. This kind of screw is called nylok screw.

Nylok screw is to use special engineering plastics and a special processing process to attach engineering plastics to the surface of the screw thread so that the engineering plastics are squeezed during the screw locking process to generate a strong reaction force and the friction between the screw thread increases. The absolute resistance to vibration completely solves the problem of screw loosening.

Another anti-loosening screw is the nylon patch screw, which is pre-coated with anti-falling screw glue and anti-falling screw. The anti-loosening glue is a high-viscosity, non-toxic, haptic deformation, water-based pre-coated thread sealant, suitable for gluing automatically. After drying, the product becomes an elastic, strong adhesion, non-curing sealant, which can be used for sealing tapered or straight threads.

The thread surface of Nylon patch screws is treated and attached with special glue, which greatly enhances the anti-loosening characteristics of the screw. It is often used in mobile precision electronic products, such as notebooks, mobile phones, and other fields.

The color Nylon patch screws can be any color like red, blue, or green depending on the customer’s application.

The Pozi drive screws were invented to further improve on the torque and cam-out of the Phillips’s head. To do this there was a second cross added to the first cross. This not only helped when distinguishing between the two head types, but it also further improved the contact of the driver to the screw.
