Our finish, or often called cup washers are a solid 651 Silicon Bronze alloy and make a great addition to their corresponding screw sizes for that clean, finished look. They not only look good, most others simply have a “bronze finish” and are plated in bronze, ours are solid silicon bronze and the right choice for a long lasting finish.
Our flat, and oval head screws have a countersunk (CSK) head that fits nicely in the cup of these washers.
