expression string from letter + number

[Lupen]

I am trying to make an expression that will call the right M thread size in a Hole feature.

For example I have an expression called SCREW_DIA = 8mm (number)
Now I would like to make another expression which calls the right thread size consisted of letter M+SCREW_DIA. The resault must be a string for example p98 = ''M8''.

Thank you for your help.

best regards
Luka
