The rosette washer, also known as a conical washer, has a conical hole in the center and appears mountain-shaped when viewed from the side. Its main role is the same as that of a flat washer, which is to prevent the sinking of the seating surface, but it is specifically designed for use with countersunk screws. When using countersunk screws, a tapered recess is required on the receiving side, but by using this rosette washer, countersunk screws can also be used on flat surfaces. Unlike metal washers, plastic washers are lightweight and do not rust, making them suitable for purposes such as weight reduction, insulation, and chemical resistance. They are also referred to as rosette washers, conical washers, or mountain-shaped washers.
