A Plain Washer is a flat, disk-shaped component with a hole in the center, typically used to distribute the load of a fastener, such as a bolt or nut, over a larger surface area. This helps prevent damage to the surface being fastened and ensures a more secure, stable connection. Plain washers also reduce the risk of the fastener loosening due to vibration and prevent corrosion by acting as a barrier between the fastener and the material. ... Made from materials like steel, stainless steel, or brass, plain washers are widely used in a variety of applications, including construction, automotive, and machinery, where durability and resistance to wear are crucial. Plain washers are essential in ensuring the proper function and longevity of metal components, bolts, and other fasteners.
