Bolt selection for different rating in one spec

Agree with what you say...now to clarify the issue further..take this example....consider the values as arbrituary please....I know the bolt lengths are no as per standard but this sort of seneio is seen with std lengths too wic i dont remember on top pf my head..so just using dummy values.

with your method how will you define the bolts in the spec so that all these four condition are satisfied when the following flanges are in one spec and the bolts also in the same or a separate bolt spec..

Do you agree that all these flanges below will use the same bolt and nuts so now the problem and the system will pick the first bolt with Dia 1/2" in the spec for calculating the total length...so question is what extra length to use which will satisfy this sorta condition...

Also assume that the Blen of BTAB uses 5mm interval for standard lengths...i.e 50mm 55mm 60mm 65mm 70mm 75mm 80mm 85mm and so on

Rat   FL-DN  Bolt-Dia  FL-Th1 FL-Th2  GT  Nut1 Nut2   xtra len   Bolt Length
150 15 1/2"   11.5   11.5   3.2  10    10  ?            60
300 15 1/2"   14.5   14.5   3.2  10 10  ?            75
600 15 1/2"   21.5   21.5   3.2  10 10  ?       80

if you agree that this is not possible, than coming back to my question, is there a way to set bolting as per flange/bolt size and rating to pick associative bolt from the spec?
