Service HotlineThe rivet nuts are divided into S series, CLS series and SP series. It provides a simple method for installing internal threads on precision metal sheet products, and plays a reliable fixing role. The small and delicate nut enables the plate to be embedded and processed on one side. When installing, just insert the nut into the hole of the metal plate. , to complete the setting firm function with pressure. When choosing to buy a rivet nut, you only need to provide a few elements: 1. Installation thickness 2. Internal thread size 3. What height do you require the nut to protrude from.
Lock washers feature easy installation. 1. Just place the helical tooth surfaces on the inner side of the two washers against each other and place them between the nut and the connecting material; 2. After the nut is tightened, the radially convex surface on the outer side of the lock washer and the contact surfaces at both ends are in an engaged state, and The angle of the slope angle of the helical tooth surface on the inner side of the washer is greater than the thread angle of the bolt; 3. When the bolt is elongated due to mechanical vibration, the nut will rotate and loosen accordingly. Because the frictional force of the outer radial convex surface of the lock washer is greater than the frictional force between the inner helical tooth surfaces. In this state, only the relative dislocation between the inner helical tooth surfaces is allowed to generate a certain lifting tension; 4. When the bolt shrinks, the helical tooth surface of the washer will make the nut return to its original position. So as to achieve 100% anti-loose and tightening effect; 5. Washers are suitable for relatively flat and smooth surfaces; 6. If the connecting material is non-metallic material, a metal plate can be fixed on the connecting material, so that the Use the lock washer; 7. There is no need to use a torque wrench when installing the lock washer; 8. You can choose to use an air tool when installing or removing the lock washer.
In recent years, more fasteners have been used in rivet nuts, which have replaced some existing welding methods to a certain extent. Rivet nuts are a way to join some difficult-to-weld equipment and other components. The use of rivet nuts requires rivet nut equipment (manual rivet nut equipment, etc.). Matters needing attention before using manual rivet nut equipment. 1. First, make sure the nozzle screws are properly assembled. According to the size of the rivet nut, select the appropriate equipment and rivet bolt. Every connecting part is not secure. 2. Confirm the deformation length or displacement of the rivet nut, and then leverage the long angle. 3. The scale ring of the rivet nut equipment is used to adjust the rivet stroke, which can be adjusted freely as needed. When adjusting the length of the rivet bolt, open the two handles and adjust the device head sleeve. The rivet bolts are exposed for a length slightly greater than the length of the rivet nut, which will eventually adjust the nut and device sleeve.
At present, the main four kinds of anti-shedding nuts are still prone to falling off. Friction and anti-shedding are in the case of shock, vibration and variable load. At the beginning, the nut will decrease in preload due to relaxation. As the number of vibrations increases, the loss of preload will increase. The force increases slowly, eventually causing the nut to loosen and the threaded connection to fail. The mechanical nut is prevented from falling off by adding a stopper, which makes it inconvenient to disassemble. The riveting and punching prevention is to prevent the separation by welding, bonding, etc. This method can only be disassembled by destroying the bolt pair.
Screw (English a screw) refers to the parts used in construction machinery. It is a kind of threaded parts with sharp ends such as nails, small cylindrical or conical metal rods, with grooved or dimpled heads, and used alone. . The detection of the screw should start from the wire of the screw. The quality of the precision screw is directly related to the wire that produces the screw. A good screw wire will open the screws more beautifully. What screw head burst, what thread is bad. Good screw wires generally do not find this situation.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: hexagon socket head shrink bolts, flat cylinder bolts, high-crore bolts, high-strength hot-dip galvanized bolts and other products, we can provide you with suitable products for you fastener solutions.
