Brass Washers

Finishing Cup washers in this selection are made of marine grade silicon bronze, which is valued for its corrosion resistance in harsh environments, and its thermal conductivity. Brass washers are suitable for use in hot and cold environments, and resistant to water corrosion, making it a staple of industries such as heating and plumbing. They are also commonly used in wood applications due to their color.

Uses

Finishing cup washers are commonly used with tapered head screws, such as flat head or oval head, to create a professional finish on the installation surface. Once installed you can see that finish cup washers create a very clean look around a screw head making it appear to be intentionally exposed, instead of just sticking out.
