About Washers

Square Washers
Square washers fit into slots and channels and have flat sides to keep them from rotating. They are wider and thicker than most round washers, making them good for distributing heavy loads.
316 stainless steel washers have excellent resistance to chemicals and saltwater. They may be mildly magnetic.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.
Black-oxide steel washers are mildly corrosion resistant in dry environments.
Zinc-plated steel washers are corrosion resistant in wet environments.
Galvanized steel washers are 10 times as corrosion resistant as zinc-plated steel washers.

Square Washers for Blind Rivets
Also known as backup washers, these square washers are for use with blind rivets for extra support when fastening into soft material. They fit into slots and channels and have flat sides to keep them from rotating. They are wider and thicker than most round washers, making them good for distributing heavy loads. They are zinc-plated steel for corrosion resistance in wet environments.

Leveling Washers for I-Beams
Commonly called beveled washers, these are tapered to fit inside an I-beam's flange to provide a parallel bearing surface.
Black-oxide iron washers have a matte-black finish that prevents corrosion in dry environments.
Hot-dipped galvanized iron washers are corrosion resistant in wet environments.
Aluminum washers are lightweight and corrosion resistant in wet environments.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.

Metric Leveling Washers for I-Beams
Commonly called beveled washers, these are tapered to fit inside an I-beam's flange to provide a parallel bearing surface.
Zinc-plated steel washers are coated for corrosion resistance in wet environments.
Hot-dipped galvanized steel washers are ten times more corrosion resistant than zinc-plated washers.
18-8 stainless steel washers are the most corrosion-resistant option.
