What is the tolerance range of precision screws?
The height of the existing assembly devices is fixed, and the height of the workers is different, so it is very inconvenient to use, resulting in a decrease in efficiency. With the progress of science and technology and the development of society, people have proposed higher assembly devices. Therefore, we propose a shaft card assembly device to solve the above problems.
④ Screw tooth type A: Self-tapping sharp tail (Japanese standard type 1) sparse AB: Self-tapping sharp tail (Japanese standard type 4) dense; B: Self-tapping flat tail (Japanese standard type 2) sparse; C: Self-tapping Tapping flat tail (the third type of Japanese standard) dense; P: double wire teeth Type triangle teeth CCT: C type triangle teeth PTT: P type triangle teeth STT: S type triangle teeth
Nuts are usually used in conjunction with bolts or screws to fasten other components and are a common and widely used component. In order to make the nut not easy to loosen and fall off when it is subjected to strong vibration and irregular strong toggling, the combined nut has appeared on the market.
In some special occasions, both objects need to be riveted and have good waterproof performance. The existing rivets have poor waterproof performance and often have problems such as water seepage.
