Washer pits and boxes vary in size and shape, but a standard for one-hole washers is 16 in Ã 16 in Ã 4 in, with a cylindrically-shaped cup (4Â½ inches in diameter and 5 inches in height) located in its upper surface.
This finishing washer, also called a trim or cup washer, has an increased bearing surface and the cupped design gives a clean finished appearance. It is round with a hole in the middle and can dress up a project while mostly hiding the appearance of the screw. The washer is designed for use with flat or oval head screws.
