Hello Clemens, it never happened to me (until now) because one experience was very memorable. When the Morgan dealer explained my first Morgan to me at pickup, it had happened to him himself when he opened the rear part of the roof. During this action the screw should not break but the roof was very tense. Actually no problem if you get the rest of the broken thread out. There was no thread insert on the 2005 Roadster. The screw was turned directly into the wood.
