Cat bolts

Douchebags at a local muffler shop installed a new muffler (i dont have a welder nor do i know how to weld) and when i got it back i noticed the nuts from the mani to the downpipe were loose, I tightened them back up. But they had loosened all of the bolts and i didnt realize it until one fell out... the front of the cat driverside bolt worked its way all the way out.

Are these the same pitch as the manifold studs? m10 1.25 pitch?

BTW ppl around here, plz do yourself a favor and dont go to Bucky's

The thread pith for *most* of these metric nut & bolts is 1.25.
