Idler pulley and tensioner bolts (PITA)

Does anyone know where I can acquire the 6mm and 12mm bolts for the belt tensioner assembly and idle pulley? Or the correct part numbers.

I have been researching them on here but confused and the part numbers I have seen say incompatible with my Tundra (2013 5.7 4x4) on various part sites and wanted to be sure.

both are a pain in the ass to get off. My belt tore and I wanted to replace everything but the bolts are tight and I’m worried I’ll strip them if they even come off. Leaning towards throwing the belt on and dealing with the other two later.

 

That is what I ended up doing, then decided I just didn't wanna mess with it and let a trusted local shop do the work so if anything went sour it was on them.
Sun devil auto in Glendale, AZ for reference, they do great work at reasonable prices and warranty all their work.
