Stainless steel studs generally need to be surface treated. There are many kinds of stud surface treatments, such as electroplating, blackening, oxidation, phosphating, and non-electrolytic zinc coating. However, electroplated fasteners account for a large proportion of the actual use of fasteners. Especially in the automotive, tractor, home appliances, instrumentation, aerospace, communications and other industries and fields are more widely used. However, for threaded fasteners, it is not only required to have a certain degree of corrosion resistance in use, but also must ensure the interchangeability of the threads, which may also be referred to herein as the screwing property. In order to simultaneously meet the "preservative" and "interchangeable" dual-use properties required for the use of threaded fasteners, it is necessary to develop special plating standards.
