Usage of spring washer
1. For general bolt connections, flat washers should be placed under the bolt head and nut to increase the pressure-bearing area.
2. For bolts and anchor bolts designed with anti-loosening requirements, the nut or spring washer of the anti-loosening device should be used, and the spring washer must be set on the side of the nut.
3. For bolt connections bearing dynamic loads or important parts, spring washers should be placed according to the design requirements, and spring washers must be set on the side of the nut.
4. For I-beams and channel steels, inclined washers should be used when using inclined plane connections to make the bearing surface of the nut and bolt head perpendicular to the screw.
