Service HotlineRivets are a commonly used fixing structure, but because rivets need to be deformed by pressure during use, it is easy to cause structural changes inside the metal, which will shorten the service life.
Principles of stainless steel screw material selection: The selection of stainless steel materials is mainly considered from the following five aspects. 1. Requirements on mechanical properties, especially strength, of stainless steel screw materials; 2. Requirements on corrosion resistance of materials by working conditions; 3. Heat resistance of materials by working temperature (high temperature strength, oxidation resistance) 4. Requirements for material processing performance in terms of production technology; 5. Other aspects such as weight, price, procurement and many other factors must be considered.
There are many names for bolts, and everyone may have different names. Some people call them screws, some people call them bolts, and some people call them fasteners. Although there are so many names, they all mean the same thing, they are all bolts. A bolt is a generic term for a fastener. A bolt is a tool that uses the physical and mathematical principles of the oblique circular rotation and friction of an object to fasten the parts of the object step by step. [1] Bolts are indispensable in daily life and industrial production. Bolts are also known as the rice of industry. It can be seen that the bolts are widely used. The application scope of bolts includes: electronic products, mechanical products, digital products, electrical equipment, electromechanical products. Bolts are also used in ships, vehicles, hydraulic engineering, and even chemical experiments. Anyway, bolts are used in many places. Especially the precision bolts used in digital products. Miniature bolts for DVD, cameras, glasses, clocks, electronics, etc.; general bolts for televisions, electrical products, musical instruments, furniture, etc.; large bolts and nuts are used for engineering, construction, and bridges; transportation equipment, aircraft, trams, automobiles etc. are used together with large and small bolts. Bolts have important tasks in industry. As long as there is industry on the earth, the function of bolts will always be important.
The technical solution of Guangdong Yueluo Hardware Industry Co., Ltd. is: Guangdong Yueluo Hardware Industry Co., Ltd. discloses an anti-dropping nut, which includes a lock, a lock plate, a nut body, a lock ring and a lock claw. The lock ring and the nut body When used together, the lock ring is a circular ring, the inner diameter of the lock ring is larger than the inner diameter of the circumscribed circle of the nut body, the outer diameter of the lock ring is smaller than the inner diameter of the lock buckle, the lock disk is an arc-shaped metal plate, and the number of lock disks is greater than or equal to three. One short side end of the lock plate is connected to the nut body, and the other end of the lock plate is connected to the lock pawl, the lock plate is inclined to the outside of the nut body, and the lock catch is arranged on the outer side of the connection end between the lock pawl and the lock plate. On the side, the lock is a concave arc.
The purpose of Yueluo is to provide a screw with a plurality of threads continuously coiled in a helical shape formed on its shank; wherein the shank is provided with a protruding cutting portion at the front section with threads toward the tip, for the purpose of providing the screw. The front section is screwed into the object to successfully complete the stage of cutting and rapid chip removal, and the rod part is provided with a concave cutting part at the rear section with threads toward the head, for the rear section of the rod to be introduced into the object. , so that the work of the stage of cutting and collecting chips can be successfully completed; so that the screw can achieve multiple functions such as labor-saving cutting, smooth and rapid chip removal and chip collection during the locking process.
