Hardened Steel Washer

A hardened steel washer is a flat, disc-shaped component made from steel that has undergone a heat treatment process to increase its hardness and strength. This enhancement makes it ideal for applications where high tensile strength and resistance to wear are essential. Hardened steel washers are commonly used in heavy-duty machinery, automotive, and construction industries to distribute loads, reduce friction, and prevent damage to surfaces. They are available in various sizes and grades to accommodate different fastening requirements. The hardness of these washers ensures they maintain their shape and functionality under high-pressure conditions. Additionally, hardened steel washers are often coated or plated to provide corrosion resistance, extending their lifespan in harsh environments.

Plain Washer

A plain washer, also known as a flat washer, is a thin, flat, circular metal disc with a central hole. It is primarily used to distribute the load of a threaded fastener, such as a bolt or nut, over a larger surface area, thereby reducing stress and preventing damage to the material being fastened. Plain washers also help in preventing loosening of fasteners due to vibration and can act as spacers. They are commonly made from materials like steel, stainless steel, brass, and nylon, catering to various industrial, automotive, and household applications. Available in multiple sizes and thicknesses, plain washers are essential components in ensuring the longevity and reliability of mechanical assemblies.
