Q:What is the nut with the flat Plate for?
A:The nut is welded to that plate and that is where the bolt screws in to it.
A:That is the first nut that the bolt screws into. The flat plate is to keep the nut from spinning so you don't need two wrenches to remove/install the bolt. The second nut is a "Lock" nut. You tighten it against the first nut to prevent the bolt from backing out later. Thermal expansion and contraction cycles in this area of the engine make the locknut a necessity.
