When it comes to stainless steel 304 screws, many customers will use the screws made from this material. So what screws can be made with the  304 series ultra coated stainless steel screws , will there be any production restrictions? The wire of the  304 series ultra coated stainless steel screws  is a bit hard, like small and long screws, stainless steel can not do. Before, some customers have customized a M1.5*60 long stainless steel screw to the Shi Shi Tong screw manufacturer. However, due to the material, it is impossible to use stainless steel for production. Finally, the customer changed the material and replaced it with iron. The screw was made. However, if the size is small and the length is not very long (such as M1.2*6), it can be produced using stainless steel. In addition, stainless steel can also produce step screws, long screws (basically from the screw specifications of M3, M4, the length of the screw is not limited), various standard screws. ...

Although there are many screw manufacturers in China, not all screw manufacturers can find  really long screws  of 100mm.

So, how do we find a long screw manufacturer that you can rest assured? When purchasing  really long screws , we will look for suppliers or manufacturers. What should we ask at the beginning of the production process they use? How did you make the long screws? The production process of long screws is nothing more than these: one is formed by welding. That is, the head and the rod are separately formed, and the head and the rod are connected by welding. There is also a cold shovel that is molded at one time using a clamping machine. This production method allows the head and the stem to be formed at one time, reducing the risk of breakage. Of course, there is another one that is proc...
