Spring Washer Usage Guide
For general bolt connections, it is essential to place flat washers under the bolt head and nut. This helps to enhance the pressure-bearing area, ensuring a secure connection.
When dealing with bolts and anchor bolts that require anti-loosening mechanisms, it is crucial to use the appropriate nut or spring washer from the anti-loosening device. Ensure that the spring washer is positioned on the nut side for optimal performance.
In applications where bolt connections experience dynamic loads or are critical components, it is important to follow design specifications for placing spring washers. Always position the spring washers on the nut side to maintain integrity.
For I-beams and channel steels, inclined washers should be utilized in inclined plane connections, ensuring that the bearing surfaces of the nut and bolt head are perpendicular to the screw.
As a leading supplier and factory in China, we provide high-quality spring washers designed to meet rigorous standards, ensuring reliability in every application.
