Worked fine - fit my track. Track is about 3/4 ". Everything down tight - yea.

These slide into the Thule Aeroblade bars without issue. I bought these to put together a custom Unistrut rack for my car and they so exactly what I was hoping, which is function just like the OEM Thule t-bolts.

Installed as channel nuts to secure crossbar solar supports on my Rhino Rack tracks on the roof of my camper. I had to wiggle these a bit to get them past the channel screws holding the channel to the roof, but I am happy with the fit. Nice to have all the extra hardware - a complete kit. Good quality, no issues at all. So far 500 miles and all secure, I’ll check them again in another 1000 miles.

At almost 30$, this is definitely on the expensive side, but these bolts fit great with the roof bars of my 2012 VW Touareg. I used them to mount an older Yakima roof box and an awning. Time will tell if the stainless steel is of good quality and if this hardware will withstand the salt that is omnipresent on the roads here in Quebec in the winter. I'll update my review in a few months.
