Washers are indispensable components in fastening systems, comprising thin discs of metal, plastic, or rubber. Serving multiple functions, including load distribution and surface protection, they accompany nuts and bolts to ensure secure and stable assemblies. Various types such as flat, lock, and spring washers offer specialized properties like vibration resistance and tension. Washers come in materials like steel, stainless steel, and nylon, catering to diverse applications across industries such as automotive, construction, and machinery. Their precise installation between fasteners and surfaces enhances stability and longevity, while adherence to stringent quality standards ensures reliability and safety in critical assemblies
