Under what circumstances can 304 stainless steel machine screws not be used with nuts?

Mr. Zhao is one of our regular customers of Shi Shi Tong. This morning he placed an order for 50,000 pieces of 304 stainless steel machine screws. During communication, Ms. Song told Mr. Zhao that stainless steel machine screws can not be used together with the same materials’ nuts sometimes.

In daily life, we often see rusty screws and nuts together, then, stainless steel machine screws in what cases can not be used with the nuts? In low-temperature pipelines, the flange has been assembled. If the stainless steel screws and nuts are tightened together, after a period of time, it is easy to bite, not easy to remove yet. For example, 304 stainless steel machine screws of the same brand cannot be used together with 304 nuts. This is because the overall structure of the thread and bolt will slightly deform after screwing, which will cause them to bite each other more tightly. And it may be because over time the screws of the same material have “fused” with the nuts.

In order to avoid the occurrence of difficult disassembly, Ms. Song told Mr. Zhao three methods:

One, the nuts can be replaced with copper material, so as to avoid the occurrence of melting.

Two, apply some grease on the 304 stainless steel machine screws and then screw the nuts.

Three, an anti-bite agent can be used to prevent corrosion, rust, and wear of parts at high temperatures.
