The function of the stainless steel flat pad is: 1. Increase the contact area between the screw and the machine. 2. Eliminate the damage of the stainless steel spring pad to the surface of the machine when the screw is unloaded. When using, it must be: stainless steel spring pad-a stainless steel flat pad, the stainless steel flat pad is next to the surface of the machine, and the stainless steel spring pad is between the flat pad and the nut. The stainless steel flat pad is to increase the stress surface of the screw. In order to prevent the screw from loosening, the stainless steel spring pad plays a certain amount of buffer protection when the force is applied. Although stainless steel flat pads can be used as sacrificial pads. But more often it is used as a supplementary pad or flat pressure pad. Stainless steel flat gaskets include enlarged flat gaskets, extra large flat gaskets, stainless steel small flat gaskets, etc. The stainless steel flat washer can increase the contact area between the screw and the machine and reduce wear and tear. The stainless steel flat washer is generally used in the joints, one is softer and the other is hard and brittle. Its main function is to increase the contact. area, disperse the pressure, and prevent the soft texture from being crushed. The materials are SUS304 and SUS316, and a large number of commonly used specifications are sold in stock. Commonly used standards are GB/T97 GB/T96 DIN125 GB848 DIN9021 and so on.
   2. The function of the stainless steel spring washer is that after the nut is tightened, the stainless steel spring washer gives the nut an elastic force, which is pressed against the nut so that it is not easy to fall off. The basic function of the spring is to give the nut a force after the nut is tightened to increase the friction between the nut and the bolt. The spring pad acts as a locking member. If the workpiece hole and thread diameter (S) are too large, do not use a flat washer or use a spring washer directly, which will not only damage the workpiece, but the most important thing is that the screw can not only fix or connect stably. Stainless steel spring washers are divided into light spring washers, heavy spring washers, saddle spring washers and standard spring washers.
