i don't know if i put this in the wrong place but i'm looking to put a tire carrier on my 4 door but i wnat to use these



but i only have 4 of them any one know what there called and where to get them i tried ace hardware and autozone but no ones seen them before.

They look like big molly bolts to me i've used to put a ladder rack on my dads pickup but he doesn't remember where he got them.
thanks

p.s. this site is great really helpful

 

Those are commonly called nutserts... Or threaded inserts.... There's a more "formal" name that I can't think if offhand. Here, we typically get them from Layton Truck Equipment and Fastenal. I'd imagine NAPA would have them, as well.

 

I would be skeptical using those to hold a tire rack on! They will only be fastening to thin sheet metal and without something to spread the weight out I would worry they will pull through your body panel. Remember a tire carrier alone is heavy then add the weight of a rim and tire plus the additional leverage when it's swung open and your looking at the potential for a couple hundred pounds of force pulling on them. I really like your thoughts on it but this is just one of those areas where I think it's way worth the extra effort and time to do it right check out my build thread for another idea I just finished installing mine.

 

thanks i never knew the name i would've went to my local fastenal but it was closed but these expand like drywall molly bolts i had like 12 but used most to install a ladder rack on my dads pick up


i was going to put about quater inch steel plate behind the panel, your thread inspired me to do it, hopefully the guy on craigslist still has the carrier, i choose to go with these because my welding skills SUCK

 

Ok good glad to hear you are putting something to reinforce it. I used 3/16 on mine and I have tried unsuccessfully to get my quarter panel to flex lol. You can pick up the steel really cheap in the hardware dept at homedepot that's where I got mine from.

 

Napa has a lot of body fasteners in their body shop supply

If you are going inside the panel anyhow to put in a plate I would likely just use a standard nut or nylon lock nut

I would also get a tube of panel adhesive (Napa) to bond the plate in place

 

good idea with the adhesive, there's a place here in dayton where i can get metal cheap like 3"x48" 1/4" thick for about 8 bucks

 

Man I wish I woulda thought of that!!!

 

I used Sikaflex to seal and bond the hinge to the rear quarter. Only problem I see with it, is that it will most likely trash the paint IF I can ever get it off again.
