Precision turning parts are magnetic, while Non-standard Precision nut is micromagnetic. Since it is weakly magnetic, can stainless steel screws eliminate the magnetism? Let's take a look with Precision turning parts manufacturers:

Ordinary Non-standard Precision nut (take austenitic stainless steel as an example), during production, the structure will be transformed into martensite, resulting in micro-magnetism, so the produced Non-standard Precision nut has magnetism. In some use environments, the screws must not be magnetic at all, and non-magnetic screws are required. At this time, we need to spend some effort on degaussing.

Generally speaking, our common method is to do high-temperature solution treatment for Non-standard Precision nut to ash the austenite structure on the inner surface of the screw, thereby demagnetizing the magnetism and obtaining stainless steel non-magnetic screws. However, it should be noted that the mechanical properties of the screws after the solution treatment will change, such as the lower degree of urethane and the higher toughness. If you have requirements on these points, you must carefully consider whether to do solid solution treatment.
