Nice... however my original answer was only security concern, not knowing if the MX4 had paddles and completely covered cord. I see many covers on the market that have just a bare cord and nothing for additional security. Nice to see the MX line does.
Yes, but nice to deter those who are dishonest as well (release latches and completely covered cord). Wish all Tonneau cover manufacturers took this into consideration.
Hope that tonneau cover has some kinda release latch or pinch sliders, instead of just an exposed latch cord to release it (for security)... since it's easy to slide something like a slim-jim under the cover in back, snag an unprotected (uncovered) cord and bob's yur uncle for bed entry. All...

Ah ha, that type. I believe if you look closely, you'll see they aren't actually threads, they are just rings that look like threads. However, you say once the screw part is pulled out, you still can't remove the grommet?
Sounds like whomever installed them at the factory, over torqued them and stripped out the plastic threads (assuming they are the same type used everywhere else automotive).
Good lord, glad you're ok man... wonder if that hit bent the frame? Has always seemed to me, after a hit like that, they are never the same after repairs. Who knows what plastic pieces suffered all through your vehicle due to this smash. Likely cracked plastic everywhere behind the scenes IMO.
