Non-Standard Bolts are widely used in the assembly of electromechanical and light industrial products. If the nut of a certain product needs to be installed outside, and the space inside is small, the indenter of the riveting machine cannot be put into the riveting and pumping. When the method cannot meet the strength requirement, then the riveting and riveting are not feasible. Must be riveted. Applicable to the field of fastening of various thickness plates and pipes (0.5MM-6MM). The pneumatic or manual rivet gun can be riveted at one time, which is convenient and firm; instead of the traditional welding nut, it can make up for the thin metal plate, the thin tube is welded and melted, and the welded nut is not smooth.
The flat head small hexagonal hex rivet nut is mainly used in the bolt connection of non-structural bearing forces, such as the connection of interior parts such as rail passenger cars, road passenger cars, boat moorings, and improved rivet nuts that can prevent spins than aircraft nut nuts. It is more excellent, and its advantage is that the weight is lighter. It is not necessary to fix the pallet nut with the rivet in advance, and the back space of the substrate can be used without any operation space.
The standard rivet nuts are M3 M4 M5 M6 M8 M10 M12. In fact, M6 and M8 are recommended. Because of the small thread, the thread can be directly tapped on the substrate. If the thread is large, the weight of the bolt is greatly increased. The connection strength increase is limited, that is, the matching is not reasonable.
