ᐅ Toilet mounting screws from the 1990s

Hello everyone,

For installing a new toilet without replacing the concealed cistern, I need the following screws (see pictures) because the ones I have are a bit too short. Can anyone tell me the correct name for these screws or, even better, where I can order them online? Or do you have any alternative solutions?

Thank you very much and best regards,
Jörg
