Where to use?
Concave Convex Washers are a type of spring washers that have a concave outer edge and a convex inner edge.Whice are used with countersunk head screws together. These washers are primarily used to provide compression preloading to various types of fasteners and joints. They are designed to have a greater range of motion in shear than traditional flat washers, allowing them to absorb more shear stress while remaining seated in the fastener and joint. This can help to improve the performance and fatigue life of fasteners and joints in dynamic loading applications.
