The purpose of the cap nut is as follows:
(1) Nuts and stainless steel hexagon slotted nuts are equipped with cotter pins, and cotter pins are equipped with perforated bolts. Used to bear vibration and alternating load, and can prevent the nut from loosening.
(2) Cap nut with insert. By screwing the nut to tap the internal thread, the insert can play the role of locking and has good elasticity.
(3) The purpose of the cap nut is the same as that of the hexagon nut. Its characteristic is that it is not easy to slip when clamping the main nut with a wrench, and it can only be disassembled with a live wrench, a dull wrench, a dual-purpose wrench (opening part) or a special square-hole socket wrench. Mostly used for rough and simple components.
(4) The nut can be used in situations where the thread at the end of the bolt needs to be capped.
(5) The cap nut can be used for tooling.
(6) Cap nuts and ring nuts can generally be disassembled by hand without tools, and are usually used in situations where they need to be disassembled frequently and the stress is not great.
(7) Cap nuts are mainly used to fix tires and front and rear axles of automobiles, tricycles and electric vehicles. They can also be used to fix the base of street lamp brackets and some mechanical equipment that are often exposed to sunlight and rain.
(8) The nut and hexagon nut are used together to lock the hexagon nut, and the effect is good. One side of the welding nut is used for welding on a thin steel plate with holes, and then connected by bolts.
(9) Cap nuts are suitable for high-strength fasteners, mechanical fasteners, furniture fasteners, vehicle fasteners, special-shaped parts for turning, cold heading special-shaped fasteners, double-headed anchor U-shaped wires, fasteners for architectural decoration and other types of fasteners, and can also be used for basic engineering, automobile and motorcycle parts, light industry, machinery, furniture, hardware tools, architectural decoration, etc.
The surface of (10) nut generally needs to be treated, including some surface treatment processes such as zinc plating, nickel plating, chromium plating and dacromet, so as to make it more rust-proof and improve the service life of fasteners. Among these surface treatment processes, chromium plating is the best one. The chrome-plated product not only has smooth and bright surface, but also has a longer rust-proof and corrosion-resistant time, which is comparable to stainless steel.
Some friends have never seen nuts, so they can't know them clearly. In fact, a nut, as its name implies, is a nut with a cover. The purpose of this cover is to prevent moisture from entering, thus preventing the nut from rusting. We usually have the opportunity to observe the tires of cars, tricycles, electric cars and other cars, or the lamp holders of street lamps, which are mostly covered with nuts. In fact, as long as we pay attention to observation, we will find very subtle things in life.
