Cup washers are indented washers used with either round or countersunk head screws. These washers are designed to create a flush finish, often seen on furniture.
Stainless steel cup washers are specialized fasteners with a concave design, used to hold countersunk screws securely while providing a clean, finished appearance.
They offer superior corrosion resistance and durability, making them ideal for high-visibility or harsh environments.
