Product application: For large equipment, it is necessary to install accessories, such as mirror, mechanical seal seat, reduction frame, etc., at this time, use stud bolts. Screw one end into the main body, and install the accessory on the other end and then install the nut. Since the accessories are often disassembled, the threads will be worn or damaged, so it is very convenient to replace the studs.

Surface treatment: Stud bolts generally require surface treatment. There are many types of bolt surface treatments, such as electroplating, blackening, oxidation, phosphating, non-electrolytic zinc coating, etc., but in the actual use of fasteners, electroplated fasteners account for a large proportion. In particular, it is widely used in industries and fields such as automobiles, tractors, household appliances, instrumentation, aerospace, and communications. However, for threaded fasteners, it is not only required to have a certain anti-corrosion ability, but also to ensure the interchangeability of threads, which can also be referred to as 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.
