Metric Finishing Countersunk Washers
Also known as dress washers, these are machined to be sturdier and provide a neater appearance than standard countersunk washers. Flat and oval head screws sit flush within them.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.
316 stainless steel washers have excellent resistance to chemicals and salt water. They may be mildly magnetic.
Black-oxide steel washers are mildly corrosion resistant in dry environments.

Notched Washers for Wood
Also called No. 10 Western Timber and Victor washers, these have large ODs to prevent screws from sinking into wood. The notches allow you to temporarily secure them with nails to keep them from rotating during installation.

Cup Washers for Oversized Holes
Cover oversized holes and the ends of tubes and pipe with these cup-shaped washers. They are zinc-plated steel for corrosion resistance in wet environments.
