Service HotlineWith the development of science and technology, human construction technology has also continued to improve. In terms of tools used in construction, it is constantly innovating and bringing forth new ideas, in order to enable personnel operating on construction sites to work more safely and efficiently; among them, screws The belt has become an indispensable auxiliary tool in the construction industry, especially for those who need to operate in a more dangerous high position. With the assistance of a nailing machine and a screw belt, it is quite convenient to screw together. Locked work to improve work safety and efficiency.
Here Yueluo eliminates the drawbacks. The purpose of Yueluo is to provide a locking screw by which the gap existing between the locking screw and a transverse hole in a locking screw can be eliminated. Yueluo achieves the proposed object with a locking screw, which has the features of claim 9 . The line connecting the centers of gravity of the respective axially continuous orthogonal cross-sectional areas of the locking screw is regarded as a line. The advantage achieved by Yueluo can basically be seen that, due to the locking screw of Yueluo, the gap between the horizontal hole of the screw and the locking screw can be eliminated. Other advantages are as follows - the insertion accuracy and surgeon time spent remain within the range to date; - the strength of the locking screw is maintained; and - the extraction of an expired broken screw is assured. The further composition of Yueluo and Yueluo is explained in more detail below by means of schematic diagrams of parts of various embodiments.
At the beginning of the quality inspection process broadcast, we ordered the cross recessed screw and screw wire material into our production screw industry. For manufacturers in the screw industry, we must first detect the wire diameter of the screw wire and the material of the screw. Generally, the wire diameter of the screw is measured by a caliper and a measuring wire. Diameter size, whether it is the same as the size ordered by yourself. After testing these, it is the testing in the production process, starting from the head of the screw, to determine the size of the head, the opposite side of the head, the diagonal angle, the depth of the cross groove, the tolerance range of the screw, and so on. These are checked with calipers. In the inspection of all aspects when rolling teeth, the main thing is whether the thread can pass the pass and stop gauge, and whether the screw thread can pass the gauge and stop. Next is the electroplating measurement problem. After electroplating, whether it meets the requirements of environmental protection and whether it can pass the time required by the salt spray. Tools include environmental testing machines and salt spray testing machines. In short, in the production and sales process of cross recessed screws, there must be necessary tools to detect the quality of screws. The summary should be summarized as follows: calipers, hardness testers, salt spray machines, environmental testing machines, pass and stop gauges, etc. .
When processing some disc parts, the mandrel is often used for positioning, and the nut is pressed on it. However, the ordinary nut cannot meet the requirements due to its small end face and poor flatness. The user needs to make the nut, and the cost is high due to single-piece production.
In view of the above problems, Guangdong Yueluo Hardware Industry Co., Ltd. aims to provide a new type of open blind rivet suitable for riveting of aluminum, steel and stainless steel sheets with foamed materials.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: spring flat nut combination, extra long screw half thread half button bolt, locking anti-fall nut, single ear washer and other products, we can provide products such as You have the right fastener solution for you.
