M72 Hot Dip Galvanized Flat Washer

Flat washers are typically thin pieces of various shapes that are used to reduce friction, prevent leaks, isolate, and prevent loosening or dispersing pressure. These components are found in many materials and structures and are used to perform a variety of similar functions. Due to the material and process limitations of threaded fasteners, the supporting surface of bolts and other fasteners is not large, so in order to reduce the compressive stress of the bearing surface to protect the surface of the connected part, it uses washers.   From the point of view of the process characteristics of hot dip galvanizing, its own anti-corrosion performance is superior. Compared with other processes, the zinc-iron alloy layer formed by this process is closer and more detailed, which can effectively block air and water, reduce the possibility of oxidation, and the protective effect is more obvious for steel and so on, effectively extending the service life   The treatment process of hot…
