Cup washers according to NF E 27-619 belong to the group of washers. They are important when countersunk screws are used for a screw connection. Due to their shape, the head of countersunk screws is countersunk flush in the cup washer.
As with flat washers, the use of cup washers distributes the contact pressure that occurs when the screw is tightened. This optimum distribution of force ensures that the screw or nut does not dig into the workpiece and the surface in the area of the screw connection is not damaged.
The cup washers are made of V4A stainless steel (full metal), which is resistant to water, humidity and weak acids.
Full metal stainless steel cup washers are mainly used in machinery, wood and hood construction. But they are also increasingly needed in the DIY or hobby sector, as well as in automotive construction. For example cup washers are used, among other things, for fastening trim parts in racing and motor sports and are so not only functional but also aesthetically a highlight.
