Summary of information:We have more than ten years of production experience in the screw industry, the main products are: small edge metal wash...

According to the process, the wing nut can be divided into cold heading wing nut, casting wing nut and stamping wing nut. According to the shape, it can be divided into two basic shapes: square wing and round wing. According to the national standard number, it can be divided into GB/T62.2-2004 Square Wing Wing Nut Wing Nut Round Wing Wing Nut Round Wing GB/T62.1-2004 Round Wing Wing Nut

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.

Washers (spring) washers, circlips are elastic pads or card lock washers a washer that prevents bolts from loosening. The working principle of lock washers is very simple. It consists of two washers. The outside is a radial relief surface, and the inside is a helical tooth surface. When assembling, the inner helical tooth surfaces are opposite each other, and the outer radial raised surface is engaged with the contact surfaces at both ends. When the connecting piece is vibrated and the bolt tends to loosen, only the inner helical tooth surfaces of the two washers are allowed to face each other. Staggered movement, resulting in lifting tension, so as to achieve 100% locking.

Contents 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.

Guangdong Yueluo Hardware Industry Co., Ltd. discloses an eccentric special-shaped rivet, which has a simple structure and is inexpensive to manufacture. The eccentric shaped rivet includes a cylindrical head and an eccentric polished rod. The diameter of the cylindrical head is larger than that of the eccentric polished rod. The eccentric polished rod is arranged at the lower end of the cylindrical head, and the axis of the eccentric polished rod is not the same as the axis of the cylindrical head. on the same straight line. The eccentric special-shaped rivet has low manufacturing cost and is easy to realize automatic assembly.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: plastic expansion rivets, 1-point screws, non-standard hexagonal thin nuts, 4.8-grade screws and other products, we can provide you with suitable tightening. Firmware Solutions.
