Summary of information:We have more than ten years of production experience in the screw industry. The main products are: toothed screws, locki...

Material broadcast Cross recessed screws are made of iron and stainless steel. Iron cross recessed screws are also called carbon steel screws. Stainless steel cross recessed screws include stainless steel SUS201 and stainless steel SUS304, and stainless steel SUS316 cross recessed screws.

In the prior art, there are also automated equipment for riveting and assembling of hardware and handles; however, for the existing automated equipment, how to automatically and efficiently realize rivet feeding is particularly important.

Cylindrical pins are widely used, and they are usually provided with matching pin holes. For the tails of cylindrical pins exposed outside the pin holes, they usually do not have a guiding function, which cannot meet the needs of quick installation of workpieces.

Make further details to make the technical scheme of Guangdong Yueluo Hardware Industry Co., Ltd. easier to understand and master. As shown in Figure 1, Yueluo is a schematic diagram of the thread design structure of the plastic screw of Guangdong Yueluo Hardware Industry Co., Ltd. It can be seen from the figure that this creation mainly controls the tooth angle of the thread. Compared with the normal tooth angle of many self-tapping screws, which are 48 degrees, 60 degrees and 34.5 degrees, the tooth angle of Guangdong Yueluo Hardware Industry Co., Ltd. The profile angle is formed by a 30-degree asymmetrical thread I. In particular, the asymmetrical thread I has a forward thread angle greater than the reverse thread angle. A more preferred embodiment is an asymmetric thread. The tooth profile angle α of the in-line installation is 20 degrees, and the tooth profile angle β of the reverse installation is 10 degrees. With this narrower non-stacked thread, the radial pressure on the plastic material is effectively reduced. In addition, the connecting bottom surface 11 between the screw teeth is designed as a circular arc surface. In the process of forming the self-tapping thread, it is more conducive to the flow of the material and the formation of the thread, and at the same time, the material can be more closely matched with the screw. Moreover, the radial pressure of the casing is relatively uniform, and the formed threads are not easily damaged. Yueluo has been tested by a series of professional parameters. Compared with other traditional screws, the plastic screws designed by Guangdong Yueluo Hardware Industry Co., Ltd. have better radial pressure, shell deformation after installation, load distribution, installation torque, drawing The force distribution, the strength of the pull-out force and the mounting torque range all show advantages. In particular, it can be installed with less torque to achieve the same clamping force and pulling force. Compared with a specific parameter, the thread strength of Delta-PT is 387N, while the thread strength of Guangdong Yueluo Hardware Industry Co., Ltd. reaches 449N. Yueluo can understand the plastic screw structure and implementation of Guangdong Yueluo Hardware Industry Co., Ltd. detailed above. It can be understood that through the improvement of the special thread structure, the radial pressure and installation torque during screw installation are reduced, and the damage to the plastic hole is reduced; And the pull-out resistance of the screw is increased, and it is not easy to appear loose in the assembly. At the same time, the design of the bottom surface of the connection between the threads of the arc optimizes the flow of the material of the installation object, which improves the integrity of the installation connection.

Guangdong Yueluo Hardware Industry Co., Ltd. has upgraded and combined the fastening nut and the hexagonal nut to ensure the original function of the nut. The nut can be easily and safely disassembled by preparing practical small parts. The inner diameter of the lock ring is 0.1mm larger than that of the hexagonal nut, which is convenient for installation.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: GB923 hexagonal cap nuts, DIN7971 round nuts, round head Phillips screws, crown screws and nuts and other products, we can provide you with suitable products for you Fastener Solutions.
