I think I damaged the threads in the roof rack mounts?

I got an OEM Subaru Roof Rack for my '21 WRX and I followed the instruction manual for installing them. They give you 4 bolts to secure the roof rack to the car, and I tightened it first by hand with the t30 screw driver and then used a torque wrench set at 60lbs as the manual said to tighten it using a torque wrench between 60-75lbs. THere was no click on the torque wrench and I felt like something was wrong so I stopped, and loosened it a bit but wanted to inspect the bolt hole in the roof as I felt something was off. I took them off and saw that there was like a cylinder like of threading loose when I took the bolts off. I tried putting the bolt back in it and tightening it by hand and now it won't stay in/grip. I switched bolts and now suddenly, it works but I'm not sure if it's safe as I cannot test if it's set at 60lbs or if the threading is secure. Obviously one bolt is damaged but one bolt hole may also be damaged. I can't rip it off when I grab it, but I don't want it to fly off on the highway. I don't know what to do, or if I can even use a roofrack anymore if the threading is sketchy.

I feel like an idiot.

“Supposed” to. But VERY few people do! I had a Mazda years back and on their forum they had a thread that was only dedicated to the torque specs of all the bolts throughout the car. “VERY few people” typically aren’t the one’s that are on car enthusiasts sites 😉

But don’t get me wrong, we can be morons from time to time!

Is there anyway to replace the threaded inserts on the WRX roof? When I installed the roof rack properly one screw wouldn't actually stay in it would come out, I had to switch it with another screw. I'm afraid to say I may have damaged the threaded insert :(. I'm not sure if it's safe to run racks now.

Hey man I am in the same situation I torqued it ft-lbs instead of nm-lbs. I think it messed up all 4 mounting spots. The reason I am assuming this is because when I am unscrewing the bolt from crossbar it just spins and does not unscrew. How did you go about fixing this. If I bring it to the dealership do you think I would need to get the replacement bracket part unwelded and get some new ones welded back on?
