Our finish, or often called cup washers are made of a solid 316 Stainless Steel (also known as A4 or 316l) alloy and make a great addition to their corresponding screw sizes for that clean, finished look. They not only look good, they will stave off corrosion much longer than 304 stainless or other "mystery" stainless steels and are the right choice for a lasting finish.

Our flat and oval head 316 stainless screws have a countersunk (CSK) head that fits nicely in the cup of these washers.

I have been buying fasteners from Fair Wind for some time now and their products never disappoint. The shipping is unparaleled and the quality exceptional.
