The problem I have with the original black screws is that it is too easy to over tighten them which strips the plastic threading and makes then nearly impossible to remove without pliers and basically just mangling them.

I wanted something that I could remove easily (and re-install) without mangling them. I originally went to the hardware store looking for some metal nuts and bolts to replace them with when I saw these anchors and decided to try them.

If you don't need to remove your grille, you'll probably never have an issue with the factory one. But, removing the grill is required to do some mods and that is where I started having issues.

 

You should not be tightening them at all. The center insert is made to just pull out and push in. The drywall screw method works real nice to pull them out. I've had my grill off over 10 times with the same fasteners and they are still holding like new.
