This characteristic is particularly important for outdoor photovoltaic systems
1. Preventing loosening: The main function of spring washers is to prevent loosening of fasteners (such as nuts and bolts) through their elasticity and oblique friction. When the nut is tightened, the spring washer is compressed, generating a reverse force that increases the friction between the nut and bolt, effectively preventing loosening 2. Reduce friction: Spring washers can also reduce friction between nuts and bolts, making fasteners less likely to loosen when subjected to vibration. This characteristic is particularly important for mechanical equipment that is frequently subjected to vibration or impact 3. Expand contact area: Although flat washers are mainly used to expand contact area and disperse pressure, spring washers can also play a similar role to some extent. Especially when the strength of the connected parts is low, using flat pads or flange bolts can increase the contact area, while spring washers can further prevent loosening 4. Special applications: In some special cases, the use of spring washers depends on specific engineering requirements.

1.A washer is a seal that fills the gap between two mating surfaces, allowing the two workpieces to be connected together without leakage even when compressed. 2.A washer can fill some irregularities on the surface, allowing for some imperfections in the mating surfaces of the workpieces. washer are generally made by cutting and splitting thin sheets. 3.Generally speaking, the ideal washer material is one that allows a certain degree of deformation so that it can deform and fill the corresponding space (including some slight irregularities) during assembly. Some washer require the addition of sealants directly to the surface in order for the gasket to work properly.

DIN935-1 hexagonal slotted nuts are mainly used to fix the front and rear axles of vehicles. By tightening the screws that pass through the front and rear axles, the frame and tires are fixed together. In order to prevent the nut from loosening, it is usually fixed by using an open-ended pin that passes through the groove of the slotted nut. The open-ended pin needs to pass through the middle of the wheel axle screw, and usually both ends of the wheel axle screw need to be drilled. The diameter of the hole and the width and depth of the slotted nut groove determine what specification of open-ended pin is selected.
