WASHERS

Steel washers are fundamental components used in conjunction with bolts and nuts to distribute the load, prevent surface damage, and provide a secure and uniform tightening in mechanical assemblies. Lincoln Structural Solutions stocks a wide variety of sizes, materials and types of washers.  Custom made sizes are available.  Contact us for more information. 

1. Material: Steel washers are typically made from carbon steel, stainless steel, or alloy steel. Each material has its own set of properties, such as strength, corrosion resistance, and temperature tolerance, making it suitable for different applications.

2. Types: There are various types of steel washers available, including flat washers, spring washers, lock washers, and fender washers. Each type serves a specific purpose, such as providing a smooth bearing surface, resisting loosening due to vibration, or distributing the load over a larger area.

3. Shapes and Sizes: Steel washers come in a range of shapes and sizes to accommodate different bolt sizes and application requirements. Common shapes include flat, square, and round washers, with standard sizes specified by diameter and thickness.

4. Functions:

   • Flat Washers: Flat washers are the most common type, providing a smooth surface under the head of a bolt or nut to distribute the load and prevent damage to the mating surface.
   • Spring Washers: Spring washers, also known as Belleville washers, provide tension to maintain bolt preload, preventing loosening due to vibration or thermal expansion and contraction.
   • Lock Washers: Lock washers, such as split washers and toothed washers, are designed to prevent loosening of fasteners by creating friction or interference between the nut and the mating surface.
   • Fender Washers: Fender washers have a larger outer diameter compared to standard washers, providing additional support and preventing pull-through in thin materials.

5. Applications: Steel washers are used in a wide range of applications across industries such as construction, automotive, machinery, and electronics. They are essential components in assembling structures, equipment, machinery, and appliances, ensuring secure and reliable fastening.

6. Corrosion Resistance: Stainless steel washers offer excellent resistance to corrosion, making them suitable for outdoor or corrosive environments. Carbon steel washers may require additional coating or plating to enhance corrosion resistance.

7. Strength and Durability: Steel washers are known for their strength and durability, capable of withstanding heavy loads, vibrations, and harsh environmental conditions. Proper selection of material and type ensures optimal performance and longevity in various applications.

In summary, steel washers play a critical role in fastening assemblies, providing load distribution, surface protection, and secure tightening. With a variety of types and materials available, steel washers offer versatile solutions for a wide range of industrial and commercial applications.
