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 17-7 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.

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.

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.

Undersized Washers

These washers distribute pressure evenly under fasteners with narrow heads, such as cheese and socket head screws. They have smaller diameters than general purpose washers of the same screw size.

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.

Clipped Washers

Clipped on one side, these washers fit in tight spots where your typical round washers can't. Position them against a flat edge, and they won't rotate out of place as you tighten. Washers take the pressure off screws and nuts to protect mounting surfaces.
