The corbel/bracket comes exactly as pictured. No mounting screws are included. This means a separate trip get them, and then finding a screw that will work is a bit problematic. Stainless screws weren't hard to find, but I wanted a flush surface and pan head screws were the only ones that would work with the straight-drilled holes. The edges of the holes needed to be beveled to countersink the screw heads, so I had to take the pieces to a machine shop to get the bottom hole tapered. The top holes were inaccessable since the support and angle prevented access.
Bottom line, the holes should be prepped for screws, and the screws should be included for the price.
The whole process - from start to finish was great. Order was on time, got email notifications and the product is wonderful.
