[HTi]Johnson Posted May 23, 2006 Share Posted May 23, 2006 what grade are the head bolts, and what type of steel? just your common steel, heat treated? Thanks, I tried searching, maybe I just missed it. Link to comment Share on other sites More sharing options...

LPGsuperchargedBrumby Posted May 24, 2006 Share Posted May 24, 2006 what grade are the head bolts, and what type of steel? just your common steel, heat treated? Thanks, I tried searching, maybe I just missed it. they're about grade 10, i hardness tested a couple (i was bored) and they're better than grade 8 but not as good as grade 12 Link to comment Share on other sites More sharing options...
NorthWet Posted May 24, 2006 Share Posted May 24, 2006 they're about grade 10, i hardness tested a couple (i was bored) and they're better than grade 8 but not as good as grade 12 Is that the "metric" grading or the US "SAE" grading? (Probably not the right terms, but I am too tired to remember properly.) Our US "metric" 8.8 bolts are roughly equivalent to SAE grade 5. Link to comment Share on other sites More sharing options...
