I believe everyone knows that Hexagon Flange Bolt (https://www.chinaweigao.com/product/bolt/hexagon-socket-head-bolt.html ) do not need nuts, but did you know? In fact, stainless steel screws and nuts cannot be used together. What is going on?

Why can't stainless steel screws and nuts be used together?

　　 When we are assembling two objects, we use stainless steel screws and nuts to fasten them. Once time passes, you will find that the screws and nuts will seize.

　　 This is because after tightening, the threads and bolts of stainless steel screws will be structurally deformed.

In addition, after a long time, the Threaded Rods And Eye Bolts ( https://www.chinaweigao.com/product/bolt/threaded-rods-and-eye-bolts.html ) and the screw holes will merge, so it is not easy to disassemble the screws and nuts in the future. Therefore, if two or more products are assembled, stainless steel screws are not recommended. Used in conjunction with the nut.
