Washers are essential components used with threaded fasteners such as screws, nuts, and bolts to distribute the load and prevent damage to the surface being fastened. Typically, a washer has an outer diameter approximately twice the size of its inner hole, ensuring even load distribution. Beyond load spreading, washers also serve various purposes such as acting as spacers, locking devices, vibration dampeners, and preload indicators in different mechanical assemblies.
These washers are manufactured in a wide range of materials including stainless steel, carbon steel, alloy steel, duplex and super duplex steel, Monel, Inconel, Hastelloy, Nickel alloys, and SMO 254. The choice of material provides strength, durability, and resistance to corrosion, making them suitable for industries such as construction, automotive, marine, petrochemical, and heavy engineering. Precision manufacturing ensures they meet international standards for performance and reliability.
A broad variety of washer types are available to cater to different requirements. These include serrated star washers, dome plain washers, conical washers, wave washers, fender washers, hillside washers, flat washers (SAE & USS), spring washers, ogee washers, square bevel washers, and finishing washers. Each type is designed for a specific application, whether it’s to provide a locking effect, reduce vibration, maintain tension, or act as a spacer in an assembly.
Washers can be customized in different sizes, shapes, and thicknesses as per the needs of specific projects. They are also available with various surface finishes like zinc plating, galvanizing, black oxide, or PTFE coating for enhanced corrosion resistance and longevity. This makes them highly versatile and suitable for both general-purpose and specialized industrial applications.
These high-quality washers are widely supplied and exported to global markets including Qatar, Bahrain, Saudi Arabia, Indonesia, Singapore, Malaysia, Turkey, UAE, Russia, Ukraine, South Africa, Australia, and the United States. Their durability, precision, and reliability make them a preferred choice for engineers, contractors, and industries requiring dependable fastening solutions.
