Roof rack anchor points

Hey everyone, just looking for some options into loading stuff on to my rack. Currently I use ratchet straps to secure my cargo to the roof, and it works really well. What I would like is some anchor points on my rack tho. I have an uptop bravo rack and I know they've got track nuts for sale, so planning on using their hardware, should I get some m6 threaded eye nuts and put them on the rack? Or maybe some v or d-rings like this?

It takes me a bit of set up and trial and error to get stuff to stay secure on my rack, id like to simplify things a little bit and make the process quicker. I have to load and unload my cargo to pull into my garage. So its not much of an option to keep my cargo secured all the time. Any tips, pics or ideas would be awesome!

 

Not sure of the exact size, but these are more or less what Prinsu sells. I use some on my rack.

If theyre similar to Prinsu and use the same type crossbars... 1/4 carriage bolts fit perfectly, whatever desired length you'd like

 

Slide the head in the track and then secure however? Nuts of whatever kind?

 

Yep, the other guy put in pretty much what prinsu includes.

The carriage bolts fit perfectly inside the tracks and then use them to secure whatever youd like, you can use the eye hooks or nuts for whatever you're doing.
