Getting ready to change my front bumper cover on my 2003 to other than stock.
I have never liked the "c clamp" type nuts that go on the bottom of the bumper cover to attach the undercover to. 10mm I think.

Has anybody ever used rivet nuts to replace those? If so, how did it work out?
I have never used rivet nuts but they look like the answer to me to some questions.
For example, it would be nice to have rivet nuts on the top of the bumper cover rather than those cheap and nasty plastic plugs.

Any input appreciated.

 

I did something similar for the top mounting points of the bumper. I used some time-sert thread repair inserts since I didn't like the plastic pop clips. I think the size I used was M10 x 1.5 x 20mm. I used my tap and die kit to cut the threads for the insert and then used some flat stainless bolts.

I didn't do this for the bottom mounting points but I imagine it would be somewhat similar.

 

Using a cheaper anchor style rivnut, have been using them for at least 5 years now. Does hold things a lot tighter. This is a older pic but still the same

 

Bottom no but I did replace the top ones with NRG fasteners, I can shoot you some pictures if you'd like. For the bottom the best thing it the factory style stuff, the nutserts will eventually strip out.

 

Thanks, good point, didn't think about them wearing out. Cheaper and easier to replace the c nuts if so.

 

I work in the field and I've seen it all, anything press fit that has to deal with the torsional stress of tightening and loosening a fastener will eventually strip. Didn't want them either but just had to bite the bullet lol.
