When I installed back the front wheel arch liner, I've applied too much torque and broke one of the studs. Looks like this is some sort of aluminum stud which is press fitted into body. Any idea how to fix it?
My knee-jerk reaction would be to drill, tap, and screw in new stud with threadlocker of some sort. If it's a pressed stud it'll be difficult to get behind it to press a new one in, I reckon. You'll probably need to get a new nut for it too, unless you pick up a stepped stud.
Colour me impressed that you managed to break a metal stud with a plastic nut, though.
I was thinking about riv nut, but I don't want to drill big hole into body. Then I thought about welding it, but I don't want to risk frying computer with electrical shock or burn some insulation inside the car.
I will give a shot to JB weld. Issue is how to hold the broken stud in place so it will not sag down by gravity before JB weld will cure. I'm thinking to drill a small pilot hole into stud / body and insert some small steel pin to hold it in place. Something like this: https://www.mscdirect.com/browse/tn/...6656139333_c_S

What do you think?
Duct tape maybe to hold it while it sets....
Even PL or Sikaflex could work probably polyurethane.... but JB weld will likely be a permanent fix...
Kwikweld sets in 6 minutes.... https://www.jbweld.com/product/kwikweld-twin-tube. Just sit there holding it with one hand while drinking a beer with the other. Then once its set you can add more material to make it stronger than new if needed.
Rumor has it there is a user on this very forum that used Kwikweld to repair a plastic bracket on his car that Porsche charges a $100+ dollars for and its been fine for almost 2 years now and still going strong....
IMO drilling a hole in the car is inviting more problems (such as ingress water..). This thing performs a simple function of supporting a fender liner, keep the repair simple.
I know someone who has JB weld holding his transmission case together (not that I support that), but it totally works.

That would work, if you can drill both holes straight, but a glob of modeling clay would also hold it in place until the JB Weld cured. But I think the best fix is a nutsert, rivnut or similar. You can also get them in metric sizes.
JB Weld will not hold. Welding or stud replacement are the only true secure fixes.
ROFL. And this is based off what? I'll bet you lunch it holds.
Fast forward to where he is drops metal plates on the stud. Then go back and look how OP needs this thing to add a tiny amount of support to a plastic fender liner.
Good video AdamSanta85. I will try JB weld original, I've use it in past. Now I need to figure out how to hold the stud in place. Also JB weld will have a tendency to flow down by gravity.
I did the same thing a few months ago. All I've gone and done for now is applied some flex seal tape over that spot. I still have the broken off stud to try and fix someday.
