2.25" or 2.5" shoulder screw

Does anyone know where we can get 2.25" or 2.5" shoulder screw? Robosource only has up to 2" shoulder screws. Thanks!

there is a vendor called whimsey tech, I believe they sell 2.25 and 2.5 screws with shoulders, just make sure it has the shoulder length you want

By “want” I believe you mean to indicate “in compliance with R21b”.
