Nylon screws, also known as plastic screws, are mostly made of nylon 66, which can also be called plastic screws. It is divided into nylon screws, PC screws, PVDF screws, PP screws, etc. according to materials. Physical performance index: 1 Torsion resistance at the joint of head and screw 2 Whether the head groove, especially the cross head, is consistent with the standard head size of the screwdriver. 3. The thread outer diameter, pitch diameter and bottom diameter of nylon screw shall be standardized. Because the water absorption of different plastics leads to the size difference in different use environments, this standard is not as strict as metal screws.
Advantages of nylon screw 1 Compared with ordinary metal screws, the biggest advantage of nylon screws is its good insulation and non-conductive. 2. In addition, due to non-metallic manufacturing, there will be no signal interference such as eddy current under the influence of current or other electrical signals. Its anti-interference advantage is suitable for communication and other industries. 3. Nylon screws have good acid and alkali resistance, and the best PVDF screws are followed by polypropylene, both of which have strong acid and alkali resistance. Compared with the first two, plastic screws have poor acid and alkali resistance. Therefore, nylon screws, especially PVDF screws, are widely used in the strong acid and alkali environment of some electroplating industries
