Our Finishing Washers are the ideal solution for creating a neat, professional finish to screw fittings while protecting the surfaces they are applied to. Designed for use with a variety of screw head types, these washers ensure that fasteners sit flush within the surface, reducing snagging and providing electrical insulation and aesthetic enhancement for your assemblies.

What are Finishing Washers?

Finishing Washers, also known as countersunk washers, are specially shaped components that work with flat or countersunk screws to create a flush, smooth appearance. They prevent direct contact between the screw head and the material surface, helping to reduce wear, eliminate movement and add a layer of protection in mechanical or electronic applications.
