Service HotlineAs 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.
The utility model relates to a connecting piece, in particular to a female and female screw used for shaping products in interior decoration. In the current decoration project, when fixing the decoration stereotyped product, the process is complicated, so labor-intensive and time-consuming, the construction cost is high, and the construction degree is low. For example, the decorative board for fixing the wall, the main process step used in its operation is the leveling of the nail strip. That is to say, saw the wood to the required specifications, then draw horizontal and vertical lines on the wall, and then nail the wooden strips to the wall according to the horizontal and vertical lines, and then glue and glue the board. The first step is to install the lines, color and paint. It can be seen that it is quite troublesome to use the above method to construct. The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a female screw, which can skillfully connect decorative products to the wall. As conceived above, the technical solution of Guangdong Yueluo Hardware Industry Co., Ltd. is a female screw, which is characterized in that both ends of the screw are threaded, the screw-in end is screwed into the plastic expansion tube inserted into the wall, and the other end of the screw is threaded with the same A female piece is mated and connected. The other end of the screw can also be barb-shaped and directly fit with the decorative board. The screw thread of the screw-in end is a wood thread, and the thread of the mating connection end with the female part is a machine thread.
A nut is a nut, a part that is screwed together with a bolt or screw for fastening. A component that must be used in all production and manufacturing machinery is divided into carbon steel, stainless steel, non-ferrous metals (such as copper), etc. several types.
High-strength self-locking nuts are a category of self-locking nuts with high strength and reliability. It is mainly based on the introduction of European technology, which is used for road construction machinery, mining machinery, vibration machinery and equipment, etc. There are very few domestic manufacturers of such products.
When using a rivet nut, drill a hole corresponding to the outer diameter of the rivet nut on the thin wall, then place the rivet nut on the bolt of the special rivet gun, push the handle to screw in the rivet nut, and put it into the drilled hole. In the workpiece, squeeze the handle, the rivet nut expands, and the deformed skirt bulges and deforms. At this time, the workpiece is tightened. After riveting, the handle is pulled out, the bolt is released from the rivet nut, and the corresponding screw is screwed into the rivet nut threaded hole. , forming a tight riveted body.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: flat end set screws, shank plum-shaped plastic head screws, cup head combination bolts, iron hexagon welding nuts and other products, we can provide you with The right fastener solution for you.
