Which it is the caliber of that screw?

if you mean the bolt size it is 3/8 course thread

Will these fit a 2004 grand am side post terminal?

Yes. If your have short bolts now You need to measure the ones you have. Dorman 60310 if you have long bolts

Will this fit my 2007 trailblazer ss

They should if your vehicles uses the side bolt. They fit my 98 Grand Prix and my 2002 Avalanche.

will these fit a 1999 pontiac sunfire?

I do not know . I bought them for a 2003 Chevy Tahoe Z71. I would think that they would be standard replacement bolt for your battery. Take the other out of your battery and measure them to get the correct one . Good luck! They where a excellent product for me....
