Service HotlineA kind of nut provided by Yueluo. The nut is in the shape of a casing and is provided with a threaded section. The hole walls at both ends of the threaded section are respectively provided with an annular shape and two grooves, and the notch of the groove points to the hole core. The hole diameter at the notch of the annular groove at the front end of the screw-in direction is larger than the nominal size of the thread segment, and the hole diameter at the notch of the annular groove at the rear end of the screw-in direction is smaller than the nominal size of the thread segment.
The embedded nut is made of copper nuts made of various embossed wires (usually lead brass, such as H59, 3604, 3602). The embedded knurled copper nuts that we come into contact with on a daily basis are processed by precision automatic lathes. The reference standard for embedded knurled copper nuts comes from the national standard GB/T809. The main operation method of the anti-loose nut is to inject the embedded knurled copper nut. After heating, it is embedded into the plastic part or directly injected into the mold. If the mold is injection-molded, the melting point of PA/NYLOY/PET is above 200°C , After the embedded nut is hot melted into the plastic part, the temperature rises rapidly. After injection molding, the plastic body rapidly cools and crystallizes and becomes hard. If the embedded nut temperature is still at a high temperature, it may fall to the place where the copper nut contacts the plastic part. Start to loosen or crack. Therefore, copper nuts are used instead of carbon steel nuts in the injection molding of embedded nuts. There are two ways to form the external knurling of the embedded copper nut. One is to use copper raw material to draw the knurl and then to produce it on the upper equipment. Generally, the pattern of this method is straight, and the other is to use The round copper material is directly embossed while tapping during the production process. This processing method can produce some non-standard size knurled copper nuts. The embossed shape of the embedded copper nut can be selected by the user, such as mesh, Character embossing, herringbone embossing and other knurling patterns.
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.

As one of the indispensable parts in automobiles, the main function of the screw is to fix the parts with through holes and the parts with screw holes together. The existing automobile screws include a screw rod and a head, and the thread pitches on the screw rod are equal. , When in use, directly screw the screw into the screw hole, so as to connect and fix the two parts, this connection method, however, when the screw has different thread spacing or part of the thread is damaged, the thread cannot be repaired and replaced. Then the whole screw will be scrapped.
