I’ve been to all of my local hardware stores but they don’t have them I believe I’ll have to special order themA washer like what, exactly? The easy answer is any hardware store. Take the old one with you for comparison. If you need more information you should state the diameter of the hole in the center and the outer diameter of the washer. Thickness may be helpful, too. Is it a plain round flat washer or is it bent in some special way? Do you want just a flat washer or a lock washer?
