Countersunk / Finishing Cup Washers - Silicon Bronze

Silicon Bronze Washers

Finishing Cup washers in this selection are made of marine grade silicon bronze, which is valued for its durability and corrosion resistance in harsh environments, including applications exposed to salt water. Silicon bronze is used in marine environments, corrosive environments, and high heat environments. Often used in plumbing and electrical applications, silicon bronze fasteners are also found on tattoo machines and in power plants. Prized for its rosy copper color, silicon bronze is sometimes used in finish applications and jewelry. Highly corrosion resistant, bronze fasteners are used for aesthetic and practical applications.

Finishing Cup Washers

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.

When you need bronze, these are great. We have an Arts and Crafts style house so I use these cup washers where needed. Not cheap but they like a lot better than brass.

Not quite sure how to review a washer. Howeverâ€”-they are well made, meet the published specs, effectively separate one item from the other and look good. The washers were appropriately packaged and delivery was as promised. I did not need all of them so I stored the remaining washers in a place where I was sure I would be able to find them again and immediately forget where I put them. I found that I need two more and unable to find the package, ordered another pack with the smallest number of washers I could get. Maybe I can start selling washers
