Product Details
The gasket is a mechanical seal between two objects, which is usually used to prevent pressure, corrosion between two objects, and leakage of natural thermal expansion and contraction of the pipeline. Due to the impossibility of machining the surface, using shims can fill in the irregularity. Gaskets are usually made of sheet materials, such as pad paper, rubber, silicone rubber, metal, cork, felt, Neoprene, rubber, glass fiber or plastic polymer (such as polytetrafluoroethylene). Gaskets for specific applications may contain asbestos. The existing gaskets are prone to deformation over a long period of use, and they cannot serve as compensation. In addition, during the use process, the sealing effect of the gasket deteriorates due to the poor adhesion between the gasket and the nut or mechanical surface.
"Spring washers can play a role in preventing loosening and increasing pre tightening force, while flat washers do not have this function. They can be used to increase the tightening contact area, prevent friction between bolts and workpieces, and protect the surface of connecting parts from scratching the surface of workpieces when bolts and nuts are tightened.
But some important connections, such as those that mainly rely on compression to generate friction and transmit power, cannot use spring pads. By reducing the rigidity of the connection, accidents can easily occur. Spring washers are not required. When the strength of the connected parts is low, flat washers or flange bolts are used to increase the contact area. When there is vibration, pulse, or significant temperature fluctuations in the medium, spring washers must be used"

Spring mattresses and spring seat cushions are commonly used and high-performance furniture items in modern times, and their cushion cores are composed of springs. It fully utilizes the advantages of good spring elasticity, good support, strong breathability, and durability. Traditional spring mattresses are made by connecting thick coils of springs with steel wires, which have a high hardness. The resulting mattress has a strong sleeping sensation and good support, but its elasticity is not obvious and it is easy to be pulled. Most of the older generation often use a connected spring bed, but if they sleep in a fixed position for a long time, sit by the bedside and corners, or flip the mattress irregularly, it can easily become concave and elastic fatigue.
"A combination screw is actually a type of screw, with only a special feature. It is usually a three or two combination component, but at least a two combination component can be called a combination screw. The main difference between ordinary screws and ordinary screws is that they are equipped with an additional spring washer or a flat washer compared to ordinary screws. In the case of three combinations, there is an additional spring washer. This is the main difference in appearance between combination screws and regular screws.
In addition to obvious differences in appearance, the main difference between combination screws and ordinary screws is their mechanical properties and usage. A combination screw is a three component or two component with an elastic flat washer, of course, it is made of ordinary screws with elastic flat washers. If you put on the flat cushion, it won't come off. Tightened into a combination. In terms of mechanical performance, a combination screw is composed of three accessories, and in terms of performance, it definitely requires three fasteners to work together. The mechanical properties of the combined screws are more secure when used. More convenient, the biggest advantage of combining screws is that it can make the production line operation convenient and fast, improving work efficiency.
The main difference between the use of combination screws and ordinary screws lies in their versatility. Ordinary screws have a wider range of uses than combination screws, and almost all industrial products use ordinary screws. Combination screws are also useful! It is only available on specific product materials. When a screw needs to be used in conjunction with a spring washer and a flat washer, a combination screw can be used"
