5/8" seems a little thin. BESRK sells some kick A$$ weld thru shackle mounts on his EBay store. IIRC, they are about $16 or $17 and they are really nice!!! You'd be best off sending him a PM. You would not regret purchasing these.
But yeah, 3/4" is pretty standard, but BESRK's 1" are no joke.

I have the one inch ones from BESRK as well, but I've seen plenty on bumpers that are well under an inch. I don't know all the engineering and technical aspects etc. but I think 5/8's would work fine. I'd bet someone here will be able to tell you for sure one way or the other though.

Look at the recovery points on the ARB TJ bumpers they look quite thin. They look to be less than 5/8" but maybe I am wrong on that.
Personally I'd go with the thickest possible connections that remain functional to eliminate weak points.
I would feel safe with the 5/8. Look what you are welding them to..... 3/16 tube. If you go all the way through you are still only welding to 3/8. The key is to make sure you leave enough material around the hole to keep the integrity of the steel.
5/8" would probably be okay for most situations.. I'd try to avoid any "side loading" to keep from possibly bending them.
The ones I make are 1"x2" hot rolled.. cut at 4.5" length with a 1" hole and rounded end... $20 for a pair or $35 for 2 pair.. shipped. PM if interested..
That is a good deal. If I hadn't gotten the buddy discount on my 3/4 inc cold rolled bars I would jump on them.
Another note on the 5/8. It is good advice to watch the side load on them. To help overcome this you can weld them in with the hole as close to the bumper as possible. This will lesson the leverage on them. Just make sure to keep them out far enough to make the most function as well.
