Metric Countersunk Washers are designed as an alternate method of preparing a flat surface for use with countersunk screws. Countersunk Washers are primarily used for aesthetic reasons, or to allow Countersunk Screws to be used with flat surfaces. These components are machined into a solid shape with a flat base, which also enhances the load-bearing capabilities of a countersunk fastener.
For a lightweight stamped variant of this component, please see Accu's Finishing Washers range.

These components can be manufactured from AccuScrews’ full range of materials, including Aluminium, Brass, Phosphor Bronze and PEEK Thermoplastic. Chemical Matte Black Coatings can also be applied to all Stainless Steel components.
