Stainless steel screws do not necessarily corrode and rust, but that stainless steel screws have a stronger ability to withstand corrosion and rust than iron screws. But stainless steel screws can still rust under certain circumstances. So under what conditions are stainless steel screws prone to rust! What is the cause of rust? Stainless steel screws have better characteristics, strong corrosion resistance, high temperature resistance, and strong rust resistance. But it will rust in harsh environments. For example, stainless steel screws are exposed to the sun and the wind every day under very humid conditions. Over time, it will definitely rust a little. For example, in contact with some acid-base chemicals to cause chemical reactions. cause corrosion and rust. There are also bad stainless steel screws, such as stainless steel SUS201 screws used in seawater. Due to long-term immersion, SUS201 stainless steel screws themselves are not suitable for use in salty seawater. cause corrosion and rust. For the use of marine products, it is generally recommended to use stainless steel SUS316 screws, because 316 stainless steel screws have better performance such as corrosion resistance. From the above, it can be concluded that stainless steel screws will still corrode and rust under certain circumstances. Therefore, this requires the rational use of stainless steel screws. Use stainless steel screws of different materials in different situations. And in different occasions, when using stainless steel screws, special attention is also required, and some details need to be considered more. Try to control the corrosion and rust of stainless steel screws as much as possible.
The round nut is often used with the round nut with a stop washer. When assembling, insert the inner tongue of the washer into the groove on the shaft, and insert the outer tongue of the washer into the groove of the round nut, and the nut will be locked; loose. Often used as the axial fixation of rolling bearings. Round nut with thread size of M10×1～M200×3. The thread specification D=M16×1.5, the material is 45 steel, the groove or all heat treatment hardness HRC35～45, the marking of the surface oxidation round nut: nut GB/T 812-88 M16×1.5.

The flat screw mainly includes a rotating part and a screw locking part, wherein the rotating part and the screw locking part are respectively flat-shaped structures; At least two sides of the screw lock portion are respectively provided with tooth rows, and the two tooth rows are mutually dislocated, so that the screw lock portion can be locked in a pre-formed screw hole in the workpiece.
