Hey all, I'm in the process of remaking a trailer. I need to attach the coupler to the trailer, but was not sure of what grade bolts to use. I was thinking of grade 8 bolts, but was not to sure. I will be getting the coupler welded on, but not until the trailer is totally finished.

 

How many lbs is the trailer? Hope this helps http://www.rockcrawler.com/techrepor...ners/index.asp

 

I'd go with grade 8 hardware....its at most only a few bucks more and well worth it for the piece of mind.

 

Yeah. Or I'd consider the purpose of the bolts to be to hold things in line while you weld...
