Actually mr. bernie sir, my local Sutherlands and Lowes both stock metric bolts of all kinds. I was needing a couple tranny bolts and a few other random bolts/nuts and after about an hour at lowes i started figuring out what all the numbers meant and figured out what i needed. NOW, i have no idea what grade these bolts are or what they are made of or any kind of strength/heat rating. All I know is that they held shit together and are still holding fine 7 months later. I might not wanna use them in extreme heat(turbo apps) or really for anything very important. I just replaced the 2 stupid top bolts of tranny and a few other fairly insignificant nuts and bolts. Just thought id throw that out there cause I was really getting frustrated with the local parts stores and other shops, and this was much easier.
