Screw Nut for Rogers Bass Drum Center Post Tom Mount Backing Plate - Londoner

This is just the screw used to tighten a center mount to the plate on the inside of a bass drum shell. Approximate outside measurement is 1 1/4”, inside 13/16”. I recently acquired used incomplete parts so listing pieces I don’t use. (In other listings are 2 other pieces, in total the plate, the mount that fits into the large hole plus the large nut to tighten- No mounting screws or other pieces). Shows some wear. Please refer to pictures, they are considered a part of the description. * last few pictures show all three pieces that I have for this assembly.
