I'm trying to find out what Size bolts I need for my Reese Hitch # 37069
I snapped the bolts a few months ago and the hitch hit the ground so I need to get new ones that are strong. Don't know if the ones that were in it were correct.

Looks like 3/4". If Lowes carries that size get some grade 8's and you'll be fine. I'd get some good washers and lock washers too.

 

Yea I read that same thread before I posted here. It's the only one I could find that even mentioned the bolts. But is that saying 9/16 head with a 1/2 inch bolt or 9/16 bolt with a 5/8 head?

Looking at the few bolts I have left i'm going to have to assume it's 1/2 inch bolts with 9/16 heads.

Definitely getting grade 8. wouldn't use anything less on a hitch. along with lock washers

 

Just measure the holes that they have to go through and thickness of the metal and stick in the largest grade 8 bolts you can find that will fit.
