I agree 100% that you should always use what the manufacturer supplies. The OP references a RECON winch and not a Warn so the fastener grades could be different. My advise would be to consult the owner's manual, website, customer service, etc.

So the bolt we can see at the front, won't back off now? If so, get a big pry bar and shove it between the plate and the bumper and get someone to now up on it while you try to remove the nut. An air or electric impact will prob be your only hope. You need pressure on the back of te nut though and I don't see another way of doing that than prying the plate and bumper apart. It shouldn't hurt anything as long as you are careful.

No, it's the rear empty spot. I was finally able to back the bolt out but now when I try to install a bolt, it only goes in half way and stops. I think because when I forced it earlier, it was going in at a slight angle due to the round gear box just slightly being in the way

...You should never use grade 8 or SS bolts for mounting a winch. There is a very good reason grade 5 bolts are used. Grade 8 is too hard and they don't flex, they sheer. Best way to kill someone and watch your winch fly off into the woods is to use something other than grade 5 on the winch. ...

I use grade 8 bolts instead of 5 all the time, shear or tensile load, winches included. Here's a manufacturer's article on the subject Grade 5 vs Grade 8 Fasteners | TineLok . They even use winch mounting as an example. The bottom line of the article is that Grade 8 is stronger in both tensile and shear, and refute the grade 8 is too hard (brittle or fatigue) assertion.
Talk to the guy that runs Rausch Creek. He's seen first hand when winch bolts sheer and the winch let's go. Same story each time; bolts replaced with off the shelf grade 8.
Obviously, it's just my opinion based on my research. I'm not an authority on the topic, but logic tells me that there is wisdom in crowds.

I don't disagree with the data. My view is that when a grade 8 fails, it snaps. When a grade 5 fails, it bends first and dissipates energy. If you talk to people in the rigging industry, they don't use grade 8 for anything. Another example is that Factor 55s locking winch bolt is grade 5 (they know a little about winching and strength).

North Sea Lifting, the largest lifting-rigging safety company in the world would disagree with your statement about grade 5 fasteners in rigging.
Rigging and lifting equipment is held to a completely different standard than what tog think.
I'm sorry to be rude to you man but you are talking out your ass.
The higher the grade, the higher the minimum yield strength, as in, the more it will give before breaking.
I'm afraid your anecdotal attitude toward metallurgy doesn't hold up to the proven science of physics.
