Use these metric washers to evenly distribute the load under bolt or screw heads and nuts when fastening. They can also act as spacers.
Stainless steel washers are more corrosion resistant than steel washers, and almost as strong. 18-8 and 17-7 PH stainless steel washers will hold up in humid, damp, and washdown environments, but will corrode if exposed to salt water or chemicals.Black-oxide 18-8 stainless steel washers have a matte-black finish. More corrosion resistant than 18-8 and 17-7 PH stainless steel, 316 stainless steel washers will not corrode from salt water, chlorine solutions, and chemicals. Stronger and slightly more corrosion resistant than 316 stainless steel, Bumax 109 stainless steel washers are best for marine environments and chemical-processing plants.
Steel washers are stronger and more wear resistant than stainless steel washers. Steel washers without a plating or coating are best for dry environments, since moisture will cause them to rust. Zinc-plated steel washers have an outer layer of zinc that protects the inner steel from rust and extends the life of the washer. Although they are stronger and more wear resistant than stainless steel, they are not as corrosion resistant. Use them in wet environments, but avoid contact with salt water and chemicals. Zinc-aluminum coated and black ultra-corrosion-resistant coated steel washers have the same level of corrosion resistance—both resist corrosion from chemicals and withstand 1,000 hours of salt spray. The black ultra-corrosion-resistant coated steel washers have a black semi-gloss finish.
At one-third the weight of steel, aluminum washers are the lightest option. They will not rust in wet environments.
In addition to resisting rust in wet environments, copper and brass washers are electrically conductive.
Washers that meet ISO 7089, 7091, and 7092 (formerly DIN 125, 126, and 433), meet international standards for fastener dimensions. The ISO 7091 washers have a slightly rougher surface than a typical flat washer.

Metric Oversized Washers
Steel
Zinc-Plated Steel
Stainless Steel
Compared to our general purpose washers, these have exaggerated diameters and/or thicknesses. Use them to cover oversized holes, hold heavy fastening loads, or as spacers and levelers.
These washers meet various DIN and ISO specifications, which are international standards for washer dimensions. ISO 8738 is formerly DIN 1440.ISO 7093 is formerly DIN 9021.
Plain steel washers are stronger, more wear resistant, and less costly than zinc-plated steel and stainless steel washers. They should not be used in wet or corrosive environments because they easily rust. Zinc-plated steel washers have an outer layer of zinc that prevents the steel from rusting in wet areas. Compared to stainless steel, they're stronger, more wear resistant, and less costly, but not as corrosion resistant. Avoid exposing them to salt water and chemicals. Stainless steel washers are more corrosion resistant than steel washers, and almost as strong. Use them in damp and washdown applications without worrying about rust. 18-8 stainless steel and 17-7 PH stainless steel washers have similar qualities to one another, except 17-7 PH stainless steel washers are stronger. 316 stainless steel washers stand up to salt water, chlorine solutions, and other chemicals without rusting. Bumax 88 stainless steel washers are the most corrosion resistant washers in our offering. They're commonly used in marine environments and chemical-processing plants.

Metric Washers for Structural Applications
These thick washers are designed to support structural screws, studs, and nuts. The steel base is hot-dipped galvanized to form a thick coating that holds up ten times better than zinc plating in wet environments. Since they are strong and rust resistant, these washers are often used for construction and on building exteriors. They meet ISO 7416 (formerly DIN 6916), which is an international standard for washer dimensions. Use them with DIN 6914 structural hex head bolts and DIN 6915 structural hex nuts.

Metal Sealing Washers
Also known as crush washers, these compress when tightened to form a tighter, more durable seal than rubber washers. They are commonly used to seal fluids such as oil and fuel. Washers are not reusable.
Copper washers are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.
Aluminum washers are lightweight and corrosion resistant in wet environments.
