What is the purpose of a washer in mechanical applications?

The purpose of a washer in mechanical applications primarily revolves around load distribution. When a fastener, such as a bolt or screw, is tightened, the washer acts to spread the load over a larger area, reducing the risk of damage to the materials being joined. This prevents localized stress concentrations that could lead to deformation or failure of the components involved. By effectively distributing the force applied by the fastener, washers help maintain the integrity of the assembly, ensuring that there is an even tension across the surface. While other functions are associated with washers, such as providing a measure of resistance to loosening, the key aspect in terms of mechanical assembly is their role in load distribution, which enhances the overall durability and performance of the joint.
