Service HotlineContents of the utility model The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a hexagon socket head screw that is easy to disassemble and assemble. In order to achieve the above purpose, the technical scheme adopted by the present invention is as follows: a hexagon socket screw, which includes a cylindrical screw head and a cylindrical screw below the screw head, the screw is provided with threads, and an integrated screw is designed between the screw head and the screw. The circular skirt pad has a hexagonal depression along the axial direction on the screw head, and is characterized in that two symmetrical flat grooves are opened on the upper part of the side wall of the hexagonal depression of the screw head, and the lines of the two flat grooves overlap. Guangdong Yueluo Hardware Industry Co., Ltd.'s socket head screws are compared with ordinary socket head screws. A notch is designed in the inner hexagon space at the top of the screw. In terms of tool use, it can be avoided that the socket head screws must be equipped with the corresponding socket head tools. disadvantages. The improved hexagon socket screw can not only use the matching hexagon socket tool, but also use the traditional flat-blade screwdriver, which is more convenient to use.
The head of the traditional screw is located outside the threaded hole and occupies a large space, which is not suitable for occasions with small space, nor is it suitable for occasions where the outer surface of the component is a working surface. For example, in the field of electronic products, or when connecting the shaft and the shaft sleeve, the machine screw with a fully threaded structure on the outer surface is widely used.
The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to overcome the above-mentioned shortcomings of the prior art, and provide a hidden screw fastener, which avoids the defect that the screw end cap is directly exposed when the traditional screw is tightened, which affects the appearance. Washers and shields hide the end caps of the screws, which are both beautiful and insulating, preventing the screws from rusting, and avoiding scratches due to burrs on the ends of the screws, which are not only beautiful but also practical and safe.
In the prior art, the hardware and the handle are generally assembled and connected by means of rivet riveting; in the process of assembling the hardware and the handle, the prior art adopts manual operation to realize the riveting and assembling process, which is time-consuming and labor-intensive. and low productivity.
In the prior art, the screw suction device can be implemented in the following two ways. One is to use a magnet to magnetize the electric bit head, and the electric bit head is used to approach the screw, and the screw is stuck by the electric bit head, so that the function of picking up the screw can be realized; The vacuum generator is used to form a negative pressure in the screw guide groove, and the screw is sucked into the tube to realize the screw pickup. The disadvantage of this solution is that in the process of picking up the screws, the grooves of the screws cannot be aligned, which leads to the deviation or leakage of the screws. The disadvantage of this solution is that the screw with an aspect ratio of less than 1.8 is prone to suction and skew, and the stability is not high. It can be seen that the existing technology still needs to be improved and developed.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: butterfly claw nuts, reducer screws, American standard and American UNF hexagon nuts, 6 hexagon head bolts and other products, we can provide you with The right fastener solution for you.
