Countersunk Finishing Washers
Countersunk finishing washers are designed to be used with flat or oval head screws. These washers come in several different styles, providing a decorative appearance and protecting your surface from being damaged by the head of the screw. These washers also offer a reliable bearing surface for flat head screws providing a more secure fit. Industry professionals often utilize countersunk finishing washers to spread force in a similar manner as a pan-head screw. The countersunk hole allows the head of the screw or bolt to sit flush with the washer creating a smooth appearance.
