Macdave Posted November 4 Share Posted November 4 I am replacing the battery box in my 1999 ch 612. Looks like it is afixed to the frame with Huck bolts. Since this isn't structural has anyone just used grade 8 bolts to reattach the battery box?

Geoff Weeks Posted November 4 Share Posted November 4 Huck's aren't any better than bolts, Rivets are stronger than bolts, but not Huck's, Go ahead and replace with bolts. Both Huck's and bolt stretch under tension and "neck", a rivet expands when compressed (set) and fills the hole. Huck's a quicker in a mfg assembly line, and can't loosen, but aren't stronger.

Joey Mack Posted November 4 Share Posted November 4 Grade 8 bolts are fine, body nound bolts ae better, if you can find them. The holes are 16mm for that batt box Quote Link to comment https://www.bigmacktrucks.com/topic/74711-battery-box-replacement/#findComment-561310 Share on other sites More sharing options...
