Service Hotlinescrew is a type of fastener that cooperates with threaded holes for combining various parts into one assembly and making the parts easy to assemble or disassemble. However, when the assembly containing the screw is used in a special environment, such as outdoor use or use in a liquid environment, there are requirements for preventing the leakage of liquid through the screw joint and preventing the screw from loosening at the screw joint. The screw structure does not have such a function. In the prior art, when there is a need for leakage prevention and loosening of the screw, a rubber washer is usually added between the screw head of the screw and the locking surface of the locked part, or the thread part of the screw is wrapped to prevent Leakage tape and then add anti-loose washers between the screw head of the screw and the locking surface of the locked part, so as to achieve the purpose of preventing leakage and loosening. However, the use of washers not only increases the thickness and weight of the assembly, but also requires an additional process during assembly, which is labor-consuming and labor-intensive. In the process of screwing, it is easy to cause uncertainty to the rubber washers due to the shear stress of the screws. Leakage occurs due to damage and deformation, and the practice of wrapping leak-proof tape around the screw teeth is often prone to damage to the threaded holes.
With 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.
Many customers ask what is the difference between a PortlandPortlandrivet nut and a PortlandPortlandrivet nut, and how to use it? Let's take a look at the difference between a PortlandPortlandrivet nut and a PortlandPortlandrivet nut with Yueluo. First of all, in terms of appearance, you can look at the differences in appearance. In terms of appearance, the difference between the PortlandPortlandrivet nut and the pressure PortlandPortlandrivet nut is still very big, but their main functions are almost the same. They all provide threads for thin plates, but the way of installation is different. The method of installation greatly determines the purpose and use of a nut. First of all, the installation method of the riveting nut is to use the riveting equipment to carry out the riveting, so it is suitable for use in the place where the riveting is not easy for the square tube and the round tube. The PortlandPortlandrivet nut also makes up for some of the shortcomings of electric welding, such as aesthetics, and places that are not easy to weld, such as thin plates.
Drilling screw is a new invention of people in recent years. A screw is a common term for fasteners, an everyday colloquial language. The tail of the drill tail screw is in the shape of a drill tail or a pointed tail, and no auxiliary processing is required. Drilling, tapping and locking can be directly carried out on the setting material and basic material, which greatly saves construction time. Compared with ordinary screws, its toughness and pull-out force and maintenance force are high, and it will not loosen for a long time after combination. It is easy to use safe drilling and tapping in one operation. Drill tail screw Drill tail screw use: It is a kind of screw, mainly used in the fixing of color steel tiles of steel structures, and can also be used for thin plate fixing of simple buildings. It cannot be used for metal-to-metal bonding. Materials and models The materials are iron and stainless steel, of which stainless steel is divided into various materials. Models are: Φ4.2/ Φ4.8/ Φ5.5/ Φ6.3mm, the specific length can be agreed upon request. According to the different drill tails, it can be divided into: round head rice / cross / plum blossom, countersunk head (flat head) / rice seed / cross / plum blossom, hexagonal washer, round head washer (big flat head), horn head, etc.
With the advancement of technology in various industries, the current structural design of screws has evolved from just simple locking to focusing on work efficiency during the locking process and not destroying the integrity of the objects to be locked. New cases such as No. 556784 screw improvement and No. 289415 screw that integrates locking, stability, labor-saving, fast and multi-function which were previously designed and approved and published in the Central Taiwan Bulletin are the main representatives of screws. It is clear that It is learned that the two cases not only fully improve the shortcomings of the traditional simple locking screws, but also achieve the purpose of substantial improvement of the screws designed in each case in actual use.
