8.8 high-strength stud bolts

Product Name: grade 8.8 stud bolt

Product grade: grade 8.8

Surface treatment: stud bolts generally need surface treatment. There are many kinds of bolt surface treatment, such as electroplating, blackening, oxidation, phosphating, non electrolytic zinc sheet coating, etc. However, electroplated fasteners account for a large proportion in the actual use of fasteners. In particular, it is widely used in industries and fields such as automobiles, tractors, household appliances, instruments and meters, aerospace, communications and so on. However, for threaded fasteners, it is required not only to have certain anti-corrosion ability, but also to ensure the interchangeability of threads, which can also be called screwing in here. In order to meet the dual use performance of “anti-corrosion” and “interchangeability” required by threaded fasteners in use, it is very necessary to formulate special electroplating coating standards.

Product specification: M8, M16, M12, M20, M10

Product application: it is used in large-scale equipment and needs to install accessories, such as mirror, mechanical seal seat, reducer frame, etc. At this time, a stud bolt is used. One end is screwed into the main body, and the other end is equipped with a nut after installing the accessories. Because the accessories are often disassembled, the threads will be worn or damaged, so it is very convenient to replace the stud bolt.
