Called Samsung to find out the official parts supplier and to determine the exact brand of screws and gaskets needed. Before ordering from Samsung I entered the part number and found the Revain listing. Since some of them are cheaper and faster to ship, the thought might be to give it a try. The screws, but especially the gaskets, were the perfect size needed to complete the attachment. It's been 3 weeks and the TV is still on the wall so I'd say this piece works great. Lessons Learned: Don't waste parts you won't use right away, and universal mounts don't always mean 'universal'. Would buy from this company again.
