Washers are essential fastening components used to distribute load, reduce surface damage, prevent loosening, and improve joint reliability. Metal washers are widely applied across machinery, automation equipment, construction, electronics, and precision assemblies. With extensive size ranges, materials, and surface finishes, they support both standard fastening needs and specialized industrial applications.
A wide variety of washer types are available to suit different functional requirements. Flat washers are commonly used to evenly distribute clamping force and protect mating surfaces. Spring washers help maintain tension and prevent loosening caused by vibration. Special shaped washers are designed for specific assembly or alignment needs, while washers with threadlocker adhesive provide added resistance against loosening without additional chemicals. Washers for fluid applications support sealing and leakage prevention in piping and hydraulic systems.
These washers are suitable for general-purpose use as well as demanding environments such as clean-room compatible assemblies and vacuum equipment, where material purity, surface finish, and performance consistency are critical.
Metal washers are offered in a broad selection of materials to match strength, corrosion resistance, and environmental requirements. Steel washers provide high strength for structural and mechanical applications. Stainless steel washers offer excellent corrosion resistance, making them suitable for food processing, medical, and outdoor use. Titanium washers (Class 1 and Class 2) combine lightweight properties with high corrosion resistance, while aluminum washers are ideal for weight-sensitive assemblies. Brass and phosphor bronze washers are commonly used in electrical and decorative applications due to their conductivity and corrosion resistance.
Various surface processing options are available to enhance durability, corrosion resistance, and appearance. Treatments such as black oxide, nickel plating, chromate plating, anodizing, and polishing improve wear resistance and extend service life. Selecting the appropriate surface finish helps ensure washer performance in high-humidity, chemical, or high-temperature environments.
Washers are available for both metric and imperial screw sizes, supporting nominal screw diameters in M (mm) and inch standards. With thickness options ranging from 0.1 mm to 45 mm, they can be precisely matched to application-specific load and spacing requirements. This flexibility ensures compatibility across a wide range of fastening systems and industrial standards.
