flat and split washer

Flat washers and spring washers are essential auxiliary components in bolted connections, playing a critical role in improving load distribution, protecting contact surfaces, and maintaining joint reliability. Flat washers are commonly manufactured from carbon steel, galvanized steel, stainless steel 304 and 316, or other specialized materials. Installed between the bolt head or nut and the assembly surface, they help prevent surface damage, reduce localized stress concentration, and provide more uniform pressure distribution. Spring washers are designed to generate additional axial tension and resistance against loosening caused by vibration, impact, and thermal expansion. These washers are widely used in industrial machinery, construction equipment, electrical panels, automotive systems, production lines, and steel structures. Manufactured according to international standards such as DIN 125, DIN 127, ISO 7089, and ISO 7090, selecting the correct washer material, thickness, and inner diameter is essential for improving connection durability, equipment safety, and overall service life.
