Stainless steel flat washers, do you know how to mark the grades?

Stainless steel flat washers are usually divided into national standard parts and customized parts. Do you know how to label stainless steel flat washers? Xiaoshuo will understand with you: Flat washers are marked as follows: GB/T 97.2-2002, flat washers d×D×B. For example: GB/T 97.2-2002, flat washers 5×12×1, which means that the washers: du003d5mm, Du003d12mm, Bu003d1mm, national standard number: GB/T97.2-2002. Flat washers are usually thin pieces of various shapes that are used to reduce friction, prevent leakage, isolate, prevent loosening, or distribute pressure. Many materials and structures have such components, which are used to perform various similar functions. Limited by the material and process of threaded fasteners, the supporting surface of bolts and other fasteners is not large, so in order to reduce the compressive stress of the pressure-bearing surface to protect the surface of the connected part, washers are used. Hardware, 15 years of craftsmanship focusing on stainless steel washers, 20,000+ sets of mold customization production experience, monthly processing capacity of 100+ sets of stamping dies, daily production capacity of 3 million punches, stamping accuracy up to 0.01mm, 16 quality inspections strictly for quality. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose rest assured!
