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

Washers for Foam Insulation
Mount insulation board to foundation walls, roofing, and framing. These washers have a large surface that distributes holding pressure evenly, so they won't crush or pull through insulation.
Galvanized Steel
More durable than plastic, these washers are strong enough to use with cement board in roofing applications.

Wave Spring Lock Washers
The wavy shape flexes like a spring to keep nuts and screws secure on slightly uneven surfaces. These washers add a small amount of tension to stop fasteners from backing out due to mild vibration. While they don't hold as well as other lock washers, they do grip slightly better than curved washers. They work best in electrical panels, light fixtures, and other light duty assemblies. Since these washers hold their shape when untightened, you can reuse them a handful of times without losing strength.
18-8 Stainless Steel—The choice for wet and outdoor environments, these washers won't rust when exposed to moisture. However, they can't hold up to the harsh chemicals that 316 stainless steel can.
3 Wave—More points of contact than single-wave washers for a better grip.
