I wouldn’t go with a larger diameter bolt where the center beam terminates at the cross bar. Yes the bolt itself will be stronger, but the web that remains (material around the hole) will be lesser. You leave too narrow a web from the hole to the edge of that channel and it will give…….

Where the two bent pieces come together on the center beam would be a good candidate for bigger bolts.
Sounds good. Thank you Sonny!

Grade 8 you think? With nylon lock washers?

I would use grade 5 or 8 of the existing size and use nylocks nuts.

The existing ones do not have any markings on them. Would that make them grade 5?

I am a big fan of nylocks and a drop of blue loctite.

Only reason I am thinking of upgrading the bolt size is the extension I had installed added quite a bit of weight to the tongue. I figured changing it to grade 8 would be good practice.

For your application I would also think either grade 5 or 8 would be fine. Grade 5 should have 3 lines on the bolt head. Grade 8 has 6 lines. Grade 8 is harder. Used in auto suspensions from what I read. Won't hurt anything using them. I also like using nyloks.

Bolt heads with no markings should be grade 2.

Wound up getting all grade 8's with ny-lock nuts.

Upped the 2 tongue bolts to 7/16, but kept the rear one at 3/8.

That's good you were able to flip the tongue around. At least that way you can put the winch post wherever you want. I unbolt my coupler to be able to squeeze my boat/trailer in the garage at an angle so my nylock nuts are shot. I only have a 10 minute drive to the ramp but I only tow early in the season and at the end when the dock is taken apart.

Good thing nylocks are cheap. lol

Thanks again for the idea of flipping the tongue around, Jeff. It took a helluva weight off my mind!! :LOL2:
