Cup Washers
Cup washers are formed washers that come in a range of styles. We provide a wide array of forms to suit the specific type you need: basic cup washers, terminal cup washers, cup washers with flanges or flat rims to fit into recesses or holes, and even countersunk washers to be used with flat head or oval head screws and bolts.
Versatile Applications
Cupped washers can be used to cover large holes, making them ideal for applications involving plumbing lines. Cup washers also serve many other purposes, such as spring retainers, centering washers, tamper-proofing, and finishing washers. Countersunk cupped washers are specifically designed to provide insulation across various configurations. Contractors often rely on these washers for both structural support and decorative purposes. In addition to their functional advantages, cup washers enhance the visual appeal of applications where appearance matters. Their cupped shape conceals screw heads, creating a clean, polished look. This feature proves useful in furniture assembly, signage, and automotive trim. Their ability to protect fasteners from environmental damage also makes them ideal for outdoor and marine applications.
Durable Material Options
Cup washers and countersunk washers are offered in materials such as Low Carbon Steel, Brass, Copper, Spring Steel, and Stainless Steel. Willie Washers offers cupped washers with finishes such as Zinc & Clear, Zinc & Yellow, Phosphate & Oil, Black Oxide, or Zinc & Black.

Basic Cup Washers
Basic cup washers provide a secure seat for fasteners, ensuring a stable and durable connection. These washers feature a cupped shape that helps distribute load evenly and prevents screws or bolts from loosening due to vibrations. Basic cup washers are widely used in mechanical and structural applications due to their ability to increase holding power.
Countersunk Finishing Washers
Countersunk finishing washers provide a sleek, professional look while enhancing the strength of a fastened joint. These washers work well with flat head or oval head screws, allowing them to sit flush against the surface.
Countersunk finishing washers also enhance load distribution, preventing material damage in delicate or lightweight components. Their smooth, flush fit ensures they do not snag on surrounding materials, maintaining a refined appearance in decorative or exposed applications.
Terminal Cup Washers
Terminal cup washers serve as insulators and reinforcement components for electrical applications. These washers create a secure barrier between the fastener and conductive surfaces, reducing the risk of short circuits or electrical failure. Their ability to resist thermal expansion and corrosion makes them ideal for electrical enclosures, circuit breakers, and industrial control panels.
