Service HotlineA double-nut self-locking fastener includes bolts, nuts, nuts, and elastic gaskets that can produce plastic deformation under pressure; the nut and the bolt are connected by threads, and one end of the nut is provided with an external thread; There is an inner thread in one end, and the inner thread of the nut and the outer thread of the nut constitute a thread pair; the other end of the nut is provided with a through hole, and the bolt passes through the through hole of the nut; when the nut and the nut are installed and tightened, the elastic gasket is located in the nut. between the bolt and the nut; a notch for cutting off the thread is arranged on the circumference of the bolt thread; the direction of the notch is parallel to the axial direction of the bolt.
The lifting ring nut refers to the part that the nut and the bolt or the screw are screwed together for fastening, and it is an original part that all production machinery must use. The lifting ring nut is a commonly used fixing pendant in engineering. There is a thread under the nut, which can be drilled according to its different specifications and fixed by the screw.
Anti-loose washers are also known as anti-loose washers, self-locking washers, self-locking gaskets, DIN25201 anti-loose washers, double-stack self-locking anti-loose washers, double-stack wedge-type anti-loose washers, etc.
The specifications of copper inserts are: internal thread specification 1/4-20, outer diameter 10mm, length 15mm mesh pattern copper nut, drawn from flower pull raw materials. The automatic lathe completes at one time: stocking → chamfering → drilling → hooking chamfering → tapping. Stable size, no eccentric internal thread. Material selection: copper C3604, Rohs PASS. The copper nut is used in injection molded parts.
In addition, in the prior art, rivets are also used to riveted screws on metal plates. The rivets are nail-shaped objects with a cap at one end. In riveting, the riveted parts are connected by their own deformation or interference. When using rivets, it is necessary to set moderately sized positioning holes in the corresponding positions of the two metal plates, and the rivets directly penetrate into the positioning holes and then riveted. Because this riveting method does not require welding, it will leave a hole on the back of the metal plate. Therefore, in the prior art, the surfaces of the two metal plates after riveting are covered with a layer of smooth metal skin to cover the riveting marks, which will also increase the overall cost, including metal The cost of the skin and the increase in the manufacturing process, while the riveting process is limited, the connection between all metal plates cannot be universal.
