Spring washer’ usually refers to a spring washer.

It is a commonly used anti loosening component in fastening connectors. By its own elastic deformation, a continuous pressure is applied to the threaded connection after tightening the bolt or nut, thereby increasing friction and preventing loosening.

There are various types of elastic pads, including standard, light, heavy, etc. Different types have differences in elasticity, size, etc., to adapt to different working conditions and connection requirements.

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.

Choosing a suitable cushion requires consideration of the following key factors:

1. Connection load and vibration situation: If the connection part bears a large load or is in an environment of frequent vibration, it is necessary to choose a spring pad with good elasticity and high strength.

2. Bolt specifications: The size of the spring washer should match the bolt specifications it is matched with to ensure effective coverage of the threaded area.

3. Working temperature: When working in high or low temperature environments, it is necessary to choose elastic pad materials that can adapt to the corresponding temperature range to ensure that their elasticity and performance are not affected.

4. Material quality: High quality materials can provide better elasticity and durability. Common materials include spring steel, etc.

5. Installation space: Consider the size of the installation area and choose a suitable size for the spring pad to avoid being unable to install and function properly due to its size being too large or too small.

6. Cost: Choose a cost-effective cushion based on the actual budget.

7. Industry standards and specifications: Some specific industries may have specific standards and specifications requirements, and relevant regulations should be followed to select elastic pads that meet the standards.
