Your go-to metal washer for every screw size. Washers take the pressure off nuts and screws to protect mounting surfaces.

Stainless Steel About Stainless Steel

18-8 Stainless Steel—The choice for wet and outdoor environments, these washers resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.

Black-Oxide 18-8 Stainless Steel—Typically chosen for their appearance, these washers have a dark, matte coating to create a finished look. They resist rust in wet and outdoor environments, but won't hold up to harsh chemicals as well as 316 stainless steel.

Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these washers won't degrade when exposed to harsh weather, salt water, and most chemicals.

High-Strength 17-7 PH Stainless Steel—Some of the strongest stainless steel washers we offer, these are comparable to high-strength Grade 8 steel. They won’t rust in wet and outdoor environments, but they can’t handle the harsh chemicals that 316 stainless steel can.

Ultra-Corrosion-Resistant Alloy 20 Stainless Steel—The most corrosion-resistant stainless steel washers we offer, these hold up in just about any environment. They won't pit or weaken when exposed to salt water and harsh chemicals, such as sulfuric acid. They’re often used in chemical-processing, battery-production, and metal-finishing equipment. Also known as Carpenter 20.

Wear-Resistant Nitronic 60 Stainless Steel—These washers have an inherently smooth surface that prevents wear. Since they don't need coating or lubricant, they're often used in particle-free environments. They also stand up to salt water and mild chemicals, such as cleaners and degreasers.

High-Temperature High-Strength A286 Stainless Steel—These washers resist high temperatures up to 1300° F. In addition, they are stronger than 316 stainless steel and withstand chemicals, such as bleach and chlorine. However, they won't hold up to salt water as well as 316 stainless steel.

Highly Corrosion-Resistant High-Strength Bumax 109 Stainless Steel—As strong as 17-7 PH stainless steel and as corrosion resistant as 316 stainless steel. These washers are commonly used in demanding environments, such as marine and chemical processing applications.

Material Certificate—Washers include a report with a traceable lot number.

Steel

Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

Zinc-Yellow-Chromate-Plated Steel—With the same corrosion resistance as zinc-plated steel, these withstand occasional exposure to moisture.

Black-Oxide Steel—Typically chosen for their appearance, these washers have a dark, matte coating that creates a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

Blue-Dyed Steel—These metric-sized washers have a distinctive blue color, so you can easily tell them apart from inch washers. The coating provides only minimal corrosion resistance, so these washers are best for dry environments.

Steel—Best for dry environments since moisture will cause these washers to rust.

Corrosion-Resistant Chrome-Plated Steel—The brightest, shiniest finish we offer, this plating has a mirror-like appearance that is often used in decorative applications. It resists salt water and chemicals better than zinc plating and is less likely to wear off.

Highly Corrosion-Resistant Zinc-Flake-Coated Steel—With 40 times the corrosion resistance of zinc-plated steel, these withstand rust as well as 316 stainless steel. They have been tested to extreme standards, including 1,000 hours of salt spray. They are similar to Magni-coated washers.

Black Super-Corrosion-Resistant-Coated Steel—Combines a finished appearance with the rust resistance of 316 stainless steel. The coating has been tested to extreme standards, including 1,000 hours of salt spray resistance, to hold up in wet and outdoor environments. Also known as black luster.

Material Certificate—Washers include a report with a traceable lot number.

For Fastener Strength Grade/Class—If you require screws or nuts with a specific fastener strength rating, make sure your washer matches the grade or class.

Aluminum

One-third the weight of steel, these washers are commonly used in robotics, automation, and other applications that have weight limits. They're an alternative to stainless steel for rust resistance, but aren't as strong.

Brass

Softer than most metals, brass washers won't damage other fastening components.

Brass—With a warm, polished look, these washers are often chosen for their appearance. Similar to 18-8 stainless steel, brass is corrosion resistant enough to stand up to wet environments.

Nickel-Plated Brass—The nickel plating offers better corrosion resistance than plain brass to stand up to solvents, salt water, and chemicals. The plating can wear off over time, so these washers are not recommended for applications that experience a lot of friction or wear.

Material Certificate—Washers include a report with a traceable lot number.

Copper

These have the best conductivity of all our metal washers. They're often used to secure electrical connections inside breaker panels and to fasten components on printed circuit boards. They're also the softest of all our metal washers, so they won't damage screws and nuts. However, copper washers aren't as corrosion resistant as brass washers, and will develop a green patina over time.

Nickel

Highly Corrosion-Resistant 400 Nickel—Commonly found in the oil and gas industries, these washers have similar strength to 316 stainless steel, but are more corrosion resistant to stand up to salt water and harsh acids. They're often used as a high-strength alternative to titanium. Also known as Monel.

Extreme-Strength 718 Nickel—Twice as strong as 400 nickel washers, these washers are comparable to our strongest steel washers. Expose them to extreme temperatures—1300° F down to -400° F—and corrosive elements, such as salt water, sulfuric acid, and other acids. Also known as Inconel 718.

Titanium

The best of both worlds, these washers are lightweight like aluminum and more corrosion resistant than 316 stainless steel.

Ultra-Corrosion-Resistant Grade 2 Titanium—Because Grade 2 titanium is 99% pure, it's even more corrosion resistant than other common titanium grades, such as Grades 5 and 9. These washers are ideal for use in chemical-processing facilities since they stand up to strong acids and other harsh chemicals.

High-Strength Ultra-Corrosion-Resistant Grade 5 Titanium—More than two times stronger than Grade 2 titanium due to the addition of aluminum and vanadium. These washers also stand up to salt water, acids, and chemicals but won’t resist harsh chemicals like Grade 2 can.

Molybdenum

Ultra-High-Temperature Molybdenum—Use these washers with molybdenum screws and nuts in high-temperature oxygen-free environments, such as vacuum furnaces. Since they’re thermally conductive, heat passes through them quickly without deforming them. They’re stronger than ceramic washers yet still handle similar temperatures without trouble. However, they will corrode in high heat when oxygen is present. They’re also nonmagnetic.
