Solid brass countesunk washers are typically used under raised countersunk or standard flat head counter sunk wood screw heads for applications which may require periodic removal of the screws, for example, a boat hatch.

Note: These have a standard 82 degree angle which is overwhelmingly the world wide standard. Square drive fasteners are usually the exception with a 90 degree angle head angle.

Note: These may be compatible for use with countersunk head machine screws provided the through hole is enlarged - e.g. a #12 gauge washer  is a sweet fit for a 6mm setscrew.

There are several wire gauge standards for the imperial measurement world.
