The Washer M20 DIN 125 HV315-390 (Part No. 80170001) is a hardened flat washer designed for commercial trailer, suspension, axle, and chassis applications. Referenced as C301389G, this precision-manufactured washer conforms to DIN 125 standards and features a hardness rating of HV315-390, making it suitable for use with high-strength fasteners in demanding heavy-duty environments.
Designed for M20 bolts and nuts, this washer provides a larger bearing surface to help distribute clamping loads evenly across the mounting material. This reduces the risk of surface damage, prevents fastener embedment, and helps maintain correct bolt preload under heavy loads and continuous vibration.
Manufactured from hardened steel, the washer is engineered to withstand high clamping forces, operational stress, and harsh transport conditions. It is commonly used in suspension systems, axle assemblies, chassis structures, and other critical fastening applications where durability and reliability are essential.
Ideal for trailer manufacturing, fleet maintenance, suspension repairs, and replacement of worn or damaged fastening hardware, this washer helps ensure secure and long-lasting assembly performance.
