    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.
    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.

    Brass
    Image of Product. Front orientation. Washers. General Purpose Washers.
    Softer than most metals, brass washers won't damage other fastening components.
    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.

    Oversized Washers

    These washers have exaggerated diameters to cover large holes and to compensate for uneven mounting surfaces. They are also thicker than general purpose washers, so they bridge wide gaps when used as spacers.

    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.
    Super-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 17-4 PH Stainless Steel—Similar strength to 17-7 stainless steel washers and comparable to high-strength Grade 8 steel. These washers won’t rust in wet and outdoor environments, but they can’t handle the harsh chemicals that 316 stainless steel can.
    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.
    Super-Corrosion-Resistant High-Strength Bumax 88 Stainless Steel—As strong as medium-strength Class 8.8 steel and as corrosion resistant as 316 stainless steel. These washers are commonly used in demanding environments, such as marine and chemical processing applications.
    Super-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.

    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 Galvanized Steel—These washers combine the strength of steel with the rust resistance of stainless steel. They're an economical alternative to 18-8 stainless steel in wet and outdoor environments, but they won't hold up to salt water and chemicals.
    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.
    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.

    Brass
    Image of Product. Front orientation. Washers. Oversized Washers.
    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.

    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.
    High-Temperature 321 Stainless Steel—The best stainless steel for high-temperature applications. These washers won't deform or lose strength when exposed to high heat up to 1500° F. They resist corrosion from mild cleaners, such as ammonia and acetone, but they can't withstand salt water or harsh chemicals as well as 316 stainless steel.

    Zinc-Yellow-Chromate-Plated Steel—With the same corrosion resistance as zinc-plated steel, these withstand occasional exposure to moisture.
    Low-Friction Cadmium-Plated Steel—The plating reduces friction between the washer, fastener, and mounting surface to prevent sticking when fastening and loosening. It also creates a barrier against rust that's comparable to zinc yellow-chromate plating.

    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.
    Corrosion-Resistant 1100 Aluminum—The best corrosion resistance of all the aluminum washers we offer. These are common in chemical and food processing industries since they stand up to salt water, mild acids, and detergents. However, they aren't as strong as 2024 aluminum.
    High-Strength 2024 Aluminum—The strongest aluminum washers we offer, these are comparable in strength to steel.
    High-Strength Zinc-Yellow-Chromate-Plated 2024 Aluminum—A winning combination of strength and corrosion resistance. These washers are as strong as steel and withstand rust better than unplated 2024 aluminum.

    Brass
    Image of Product. Front orientation. Washers. Mil. Spec. Washers.
    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.
    Black-Oxide Brass—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 salt water and harsh chemicals.
    Conductive Tin-Plated Brass—An economical alternative to copper. The tin plating improves the conductivity of these washers, so they're good for securing electrical equipment inside panels and enclosures.

    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.
    Low-Friction Cadmium-Plated Copper—The plating reduces friction between the washer, fastener, and mounting surface to prevent sticking when tightening and loosening. It also creates a barrier against rust.

    SAE Washers

    Originally designed for the automotive industry, these washers conform to SAE sizing standards. They generally have smaller diameters than USS washers to fit in cramped spots and are thinner to create more precise gaps. Washers distribute pressure under screws and nuts to protect your mounting surface.

    Super-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.

    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.

    USS Washers

    These washers meet USS sizing specifications and typically have larger diameters than SAE washers. As a result, they accommodate larger screws and nuts and distribute pressure across a wider surface area. They are also thicker, so they withstand heavier loads and span wider gaps when used as spacers.

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

    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.

    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.
    High-Strength 17-4 PH Stainless Steel—Similar strength to 17-7 stainless steel washers and comparable to high-strength Grade 8 steel. These washers won’t rust in wet and outdoor environments, but they can’t handle the harsh chemicals that 316 stainless steel can.

    Tension-Indicating Structural Washers

    Fasten structural screws and nuts securely without overtightening. When you see orange dye, you'll know you've applied the correct tension, so you don't accidentally strip threads. These washers distribute pressure under fasteners in columns, joists, and I-beams. They are tested and certified to meet industry standards for handling high-stress loads.

    Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
    Steel—Best for dry environments since moisture will cause these washers to rust.
    Corrosion-Resistant Galvanized Steel—These washers combine the strength of steel with the rust resistance of stainless steel. They're an economical alternative to 18-8 stainless steel in wet and outdoor environments, but they won't hold up to salt water and chemicals.
    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.

    These washers are manufactured and tested to strict U.S. military standards for material and construction. They are lightweight, nonconductive, and naturally rust resistant. Commonly used in electronics and automation applications, they take the pressure off screws and nuts to protect mounting surfaces.
    Nylon—The most popular plastic washers, these are strong, durable, and economical. Nylon will swell and weaken when exposed to moisture, so these washers are best for dry environments.
    Chemical-Resistant High-Temperature PTFE—The most chemical-resistant plastic washers we offer, these stand up to the widest range of harsh acids, bases, solvents, and corrosive cleaners, even at temperatures up to 500° F. Their slippery surface reduces friction between the washer, fastener, and mounting surface to prevent sticking when tightening and loosening. They are also good electrical insulators.

    Oversized Washer Assortments

    Image of Product. Front orientation. Washers. Oversized Washer Assortments.
    Keep a collection of washers on hand with exaggerated diameters to cover large holes and to compensate for uneven surfaces. These washers are also thicker than general purpose washers, so they bridge wider gaps when used as spacers. Labels in the lid include our part numbers, so it's easy to replenish the assortments.
    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.
    Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
