Service HotlineRiveting products provide great convenience for the unilateral connection of sheet parts, fast and efficient connection without bulky installation tools, and produce reliable standard internal and external threads, achieve cold installation after surface treatment, no pollution, is welding Effective alternative to nuts. Main applications: Auto-body, seat belt systems, bumpers, airbag systems, etc. 1. One-way drawing connection 2. Build standard internal and external threads 3. General product range: M3-M124. Materials: Carbon Steel, Stainless Steel, Aluminum 5. High quality air tools - efficient, economical, lightweight and easy to operate. Use the same principle as hand rivet nuts.
Use performance self-tapping screws for self-tapping screws with a diameter of 0.8mm to 12mm. For this type of screw, it generally has a high hardness. Self-tapping screws must be screwed into the test, that is, screw the screw into a test plate to check whether the hardness of the screw meets the standard. The shape of the drill tail, the hardness of this kind of screw is very strong. Compared with ordinary screws, it not only has better maintenance ability, but also has a very strong effect in connecting objects. For screws with this performance, it is generally not necessary. Auxiliary processing can directly drill a hole on the object and lock it into the object, which is not only very convenient to use, but also greatly improves work efficiency. This kind of drill screw can be said to be the first choice of the staff in various fields.
rivet is a nail-shaped object used to join two parts or components with a through hole and a cap on one end. In riveting, the riveted parts are connected by their own deformation or interference. There are many types of rivets, and they are informal. In today's product production, the slot holes on the same mounting surface often have different mounting slot depths. If a mechanical tool is used for quick screwing and installation, it will directly bring destructive effects to the brittle products, resulting in When the product is cracked and damaged, when connecting plastic shells, lightweight boards, insulating materials, circuit boards, or any other thin and light materials, the requirements for the installation process are also relatively high. The gripping force and bonding force of rivets are weaker than those of rivets that are screwed and installed by machinery. The bonding strength of rivets used in manual operations needs to be enhanced. The rivet structure needs to be improved and enhanced when installing thin, light-weight materials.
The first person to describe the spiral was the Greek scientist Archimedes (c. 287 BC - 212 BC). An Archimedes screw is a huge spiral contained in a wooden cylinder that is used to irrigate fields by raising water from one level to another. The real inventor may not be Archimedes himself. Maybe he was just describing something that already existed. It may have been designed by the skilled craftsmen of ancient Egypt for irrigation on both sides of the Nile. In the Middle Ages, carpenters used wooden or metal nails to attach furniture to wooden structures. In the 16th century, nail makers began producing nails with a helical thread, which were used to connect things more securely. That's a small step from these kinds of nails to screws. Around 1550 AD, the metal nuts and bolts that first appeared in Europe as fasteners were all made by hand on a simple wooden lathe. Screwdrivers (screw chisels) appeared in London around 1780. Carpenters have found that tightening a screw with a screwdriver holds things in place better than hitting with a hammer, especially with fine-grained screws. In 1797, Maudsley invented the all-metal precision screw lathe in London. The following year, Wilkinson built a nut and bolt making machine in the United States. Both machines produce universal nuts and bolts. Screws were quite popular as fixings because an inexpensive method of production had been found at that time. In 1836, Henry M. Philips applied for a patent for a screw with a cross recessed head, which marked a major advance in screw base technology. Unlike traditional slotted head screws, Phillips head screws have the edge of the head of the Phillips head screw. This design makes the screwdriver self-centered and not easy to slip out, so it is very popular. Universal nuts and bolts can connect metal parts together, so by the 19th century, the wood used to make machines to build houses could be replaced by metal bolts and nuts. Now the function of the screw is mainly to connect the two workpieces together and play the role of fastening. The screw is used in general equipment, such as mobile phones, computers, automobiles, bicycles, various machine tools and equipment, and almost all machines. need to use screws. Screws are indispensable industrial necessities in daily life: extremely small screws used in cameras, glasses, clocks, electronics, etc.; general screws for televisions, electrical products, musical instruments, furniture, etc.
Guangdong Yueluo Hardware Industry Co., Ltd. is a kind of locking nut, which includes a nut, the bottom of which is circular, the middle is hexagonal, the top is circular, there is a bolt hole in the center, the side wall of the bolt hole is threaded, and the top of the nut is Set up several squash notches. According to the locking nut of the preferred embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the number of flattening notches is three. The three flattening gaps can be used as the focal point of the tightening tool and the clamping place of the anti-loose gasket bayonet, and the structure is simple and can be formed by die stamping at one time.
