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

September 29, 2024
We know that Self-tapping Screws do not need nuts. Because it is naturally cool to prevent loosening. But you have heard that Stainless steel screws cannot be used with nuts. Why is this?
 
The reason for this statement is that when assembling low-temperature piping flanges, stainless steel bolts and nuts are used to tighten, and they are easy to bite after a period of time. This is because after tightening, the overall structure of the screws and bolts will undergo slight deformation, the bite will become tighter, or the screws and bolt holes will fuse after a long time.
 
At this time, if you want to remove the bolts and nuts again, you will need more force to overcome the friction of the threaded connection and overcome the energy generated by material deformation and destruction of intermolecular polymerization. In short, it will become particularly difficult.
 
① The material of the nut can be replaced with a copper nut to avoid fusion.
 
② Apply some grease to the screw before tightening the nut.
 
③ Anti-bite agent can be used to prevent corrosion, sintering, rust and wear of parts under high temperature conditions.
