IIRC they be 10x1.0@ 30mm long ...but I could be wrong 
best thing is to take one with you ...its in the metric isle and get a grade 5 or better |

Note Grade 5 or 8 apply only to inch size bolts. Property class (PC) 8.8, 9.8, 10.9 apply to commonly used metric bolts (Europe and US - not Japanese).
FWIW, PC 10.9 (1040 MPa) and Grade 8 have the same ultimate tensile stress level at 150,000 psi.
Back to your regular scheduled programming.

All very true...but living this past 15yrs in a small hick town in the Sierras..I've learned to dilute my metric to a more palatable for of local "pidgeon" if thar's one familiar term in there it cuts down on the blank stares 
Sorry...a little local speak bled thru |

If the original poster is asking about the bracket bolts the attach the bumper brackets to the frame rails they are M12 x 1 pitch. From ETKA, part number is N 010 120 3. I ran into this with my custom hitch I fabricated. I had to get longer bolts from the local bolt house. I added a bumper bracket extension an added a 3rd side bolt. Hope that helps |

| It has been brought to my attention I mistyped the thread pitch. I recall using VW scirocco lug bolts for mock up. I believe they are 1.5 pitch. |
