Description Form D washers manufactured from A2 stainless steel to DIN 125, designed to distribute the load of a threaded fastener over a larger surface area. Form D washers feature a larger outside diameter than Form A and Form B washers, combined with a reduced thickness, making them ideal where increased load spreading is required but installation space or thread engagement is limited.
Manufactured from corrosion resistant A2 (304) stainless steel, these washers provide a secure bearing surface between the fastener and the material being fixed, helping to reduce pull-through, surface damage and localised loading in both internal and external environments.
