This is a drawing of a replacement part purchased in 2001. I cannot guarantee it is exactly as original, but it is certainly functional. My replacement part has a slightly larger diameter screw, 0.150-inch diameter (3.8-mm), and I have no idea what thread it has. It does have a matching hex nut, but no washers. The original #6 screw would be 0.138-inch diameter, and the curl on the bracket may originally be slightly smaller.
