They also make Pem nuts (pressed in nuts), floating pem nuts/studs (allow for misalignment), PEM spring loaded thumbscrews. I used some of the pem studs on my firewall. It makes it so you can have threads in a thin part without using rivnuts and reducing the need for loose nuts (or in areas where you can't reach the back side for a nut).
I plan to offer the lights, mesh, and the little tabs to mount the lights. I've actually had the quote for the grill for over a month but wanted good pics to go along with the product offering instead of a pic of a loose part with some hand waving involved.
