If there is no order, do not keep inventory, otherwise it may become scrap copper and aluminum, which is a huge waste. The main thing is that when you buy copper wire rod and aluminum wire rod, you only order raw materials if you have a certain order. It is a tool to use the physics and mathematics principles of the oblique circular rotation of the object and the friction force to gradually fasten objects and parts.
Aluminum scraps and copper scraps are very easy to stick in the mold cavity and cause product scratches. Non-standard screws are used in special sizes that are not within the national standard, and are generally used for applications with fewer parts.
Screw is a tool that uses the physics and mathematics principle of the oblique circular rotation of the object and the friction force to gradually tighten the objects and parts.Screws are common in daily life. This can reduce the chance of sticking. They are the foundation of fastening everything.Similarly, if the screw pitch is small, the rotation of the same angle, the smaller the distance traveled in the radial direction, so it is relatively tighter.
It wholesale Machine Screw Factory is resistant to acids, alkalis, and other solvents, and will not oxidize and corrode the metal, so the anti-dropping and anti-loosening screws will not rust, The peeling phenomenon of the electroplating film contributes to the requirements of light weight, weather resistance and high quality of the product.
Because this special engineering plastic on the anti-dropping and anti-loosening screw has strong elasticity and memory ability, the anti-dropping and anti-loosening screw can be disassembled repeatedly 5 to 50 times, and the anti-loosing function of the anti-dropping and anti-loosening screw still exists..
