What is a Plain Washer?
A plain washer, also known as a flat washer, is a thin, disc-shaped component with a central hole, designed to be placed between a bolt head or nut and the surface being fastened. Its main function is to evenly distribute the load of the fastener, minimize surface wear, and reduce the risk of loosening caused by vibration. At Nilkamal Fasteners, our plain washers adhere to globally recognized standards such as TUV NORD - BS EN 14399 & 15048, TUV NORD - AD 2000 Merkblatt, NABL ISO/IEC 17025, ISO 9001, and ISO/TS 16349. These certifications guarantee that each washer we produce meets stringent benchmarks for quality, safety, and performance, making them suitable for demanding industrial environments.
