Trailer Anchor Points

I’m looking for some advice. I just got a trailer from my father in law. It’s a primarily metal trailer, with wood on the floor in strips, maybe 1.5 ft wide on the left and right. All of the walls on the trailer are removable so I’m not sure they would be good to use as anchor points.

Would something like this into the wood floor be strong enough to use with tie-downs? 4 would be the plan.
