Flat washers are generally used in connectors, one of which is soft and the other is hard and brittle. Its main function is to increase the contact area, disperse the pressure, and prevent the soft texture from being crushed. The basic function of the spring of the spring washer is to give a force to the nut after the nut is tightened to increase the friction between the nut and the bolt! The material is 65Mn (spring steel), the heat treatment hardness is HRC44~51HRC, and the surface is oxidized.
Blind rivets are a type of flying rivets for single-sided riveting, but they must be riveted manually, electrically, and automatically using special tools. This type of rivet is especially suitable for riveting occasions where it is inconvenient to use ordinary rivets and must be riveted from both sides, so it is widely used in construction, automobiles, ships, aircraft, machinery, electrical appliances, furniture and other products.
