Washers

Steel Washers:

Steel washers are versatile and widely used in various applications due to their strength and durability. They come in different types such as plain washers, spring washers, and lock washers. Plain steel washers provide a smooth bearing surface, while spring washers offer a preload to prevent loosening. Lock washers, such as split and toothed lock washers, provide additional security by resisting loosening under vibration.

Stainless Steel Washers:

Stainless steel washers are highly corrosion-resistant and suitable for outdoor, marine, and harsh environments. They are available in various grades such as 304 and 316, offering different levels of corrosion resistance. Stainless steel washers are commonly used in industries where hygiene and durability are crucial, such as food processing, pharmaceuticals, and marine applications.

Brass Washers:

Brass washers offer excellent corrosion resistance and aesthetic appeal due to their golden color. They are often used in decorative and electrical applications where conductivity and appearance are important. Brass washers can be used with brass screws and fasteners to create a visually appealing finish, making them popular in architectural and interior design projects.

Copper Washers:

Copper washers are known for their high thermal and electrical conductivity, making them ideal for electrical connections and heat transfer applications. They are resistant to corrosion and oxidation, ensuring long-term performance even in demanding environments. Copper washers are commonly used in automotive, electrical, and plumbing applications where reliable conductivity is essential.

Aluminum Washers:

Aluminum washers are lightweight yet durable, making them suitable for applications where weight reduction is important. They are corrosion-resistant and often used in aerospace, automotive, and electronics industries. Aluminum washers are available in various thicknesses and sizes, providing flexibility for different fastening and sealing requirements.

Titanium Washers:

Titanium washers offer exceptional strength-to-weight ratio and corrosion resistance, making them ideal for aerospace, marine, and high-performance applications. They are lightweight yet incredibly strong, providing reliable fastening and sealing capabilities. Titanium washers are often used in critical assemblies where durability and reliability are paramount.

Zinc Washers:

Zinc washers are coated with a layer of zinc to enhance corrosion resistance and provide a protective barrier against environmental elements. They are commonly used in outdoor and marine applications where exposure to moisture and corrosion is a concern. Zinc washers come in various types, including flat washers, fender washers, and finishing washers, offering versatility for different applications.

Nickel Washers:

Nickel washers offer excellent corrosion resistance and durability, making them suitable for harsh environments and chemical applications. They are commonly used in industries such as petrochemical, automotive, and manufacturing where resistance to corrosion and chemicals is critical. Nickel washers can be plated or coated for added protection and aesthetic appeal.

SIZE:

• Small: Small washers typically have an outer diameter (OD) of around 1/4 inch (6.35 mm) or less. They are commonly used in light-duty applications or where space is limited.

• Standard: Standard-sized washers usually have an outer diameter ranging from 1/4 inch (6.35 mm) to 2 inches (50.8 mm). These are the most commonly used washers and are suitable for a wide range of fastening tasks.

• Large: Large washers have an outer diameter greater than 2 inches (50.8 mm). They are used in heavy-duty applications where a larger surface area is needed to distribute the load effectively.

• Flat vs. Lock Washers: Washers can also be categorized based on their shape and function. Flat washers have a uniform thickness and are used to create a smooth surface under the head of a bolt or nut. Lock washers, such as split washers or toothed washers, are designed to prevent loosening of fasteners due to vibration or torque.
