Stainless steel 14.9 grade screws have a hardness of 36-38HRCO. Screws are tools that use the physical and mathematical principles of the inclined circular rotation and friction of objects to gradually tighten mechanical components. The main function of screws is to connect two workpieces together and tighten them. Screw, also known as "screw" or "screw rod" by some people. Actually, screws are a general term, and screws and screw rods are different from each other. Screws are generally called wood screws; It is the type with a pointed tip at the front end, with a larger pitch, and is generally used to fasten wooden and plastic parts. Screw rod is a machine screw (mechanical screw), which is the type with a flat head at the front end, with a small and uniform pitch, and is generally used to fasten metal and machine components.
