Cup Washers Stainless Steel
Description
Cup Washers – Stainless Steel
Stainless steel cup washers, also known as countersunk or finishing washers, are specially designed washers featuring a rounded, cup-shaped profile that provides a neat and finished appearance to countersunk fasteners. These washers distribute the load of the fastener over a wider surface area while enhancing the aesthetic appeal of the assembly, making them ideal for visible or decorative applications.
Manufactured from corrosion-resistant stainless steel (commonly grades 304 and 316), cup washers offer excellent durability and resistance to rust, chemicals, and harsh environmental conditions. Their unique shape helps protect softer materials such as wood, plastic, or composites from damage caused by fastener heads, reducing the risk of cracking, splitting, or surface deformation.
Key Features:
Load Distribution: The cup shape spreads the fastener load evenly to prevent surface damage and increase joint stability.
Enhanced Appearance: Provides a clean, professional finish for countersunk screws and bolts, ideal for visible hardware.
Corrosion Resistant: Stainless steel construction ensures longevity and performance in marine, outdoor, and industrial environments.
Material Protection: Helps protect softer substrates from fastener head damage, extending the life of the assembly.
Versatile Sizes: Available in various diameters and thicknesses to suit a range of fastener sizes and applications.
Typical Applications:
Architectural and decorative fittings
Marine and boating hardware exposed to harsh environments
Furniture assembly and cabinetry
Automotive and machinery where a polished finish is required
Electrical enclosures and equipment
Stainless steel cup washers combine functionality with aesthetic appeal, offering a reliable and attractive solution for securing countersunk fasteners while protecting materials and maintaining structural integrity.
