I'm installing a floor and want to retain my cargo lashing points (if not as d-rings, as threadable inserts). Anybody know offhand what the size/thread pitch is? My quick look with a thread gage suggested metric. Thanks!

It's metric for sure. I don't rember the size and pitch but just bring one of the bolts to HD or Lowes and match it up. It's a very common metric size. I bought longer ones as I recall for some reason that escapes me now.

The bolts are easily removed from the D rings, for that matter, if you need or want a hex head instead of the Star

It is ISO standard M8x1.25. Unscrew one of them to see what length you need. The replacement need not be a torx head.

I use hoist rings on my VW, but they would be the same in a PM.
They are expensive, but they are load rated, and swivel for the load.

You can get D-rings for much much less, are stamped construction, but they have less of a load limit, usually half the strength for a given thread size:

For what its worth, I would not trust much load to the single nut welded to the thin sheet metal under the van with more than the current D-rings are rated (about 500lbs). I'd do some serious reinforcement before going so far as to put in something load rated...things are only as strong as the weakest link!

Thanks for the thread info folks!

You can always double nut underneath the weldnut.
fwiw, if you want to ensure secure loads, you will want to put in an engineered load floor:

The Handifloor linked, is TUV tested, but just for a single wheelchair and occupant load.
Expediter's should install additional bolted connections, in addition to the glued connection.
