I've found that the well nuts' flange is too small/soft and they can get squeezed into the hole and you'd have to do some major disassembly to retrieve them. I don't really want to glue them to my car and the rubber is eventually going to rot. These are just as solid (they do break when you step on them) and they snap in and out in seconds - no need for screws or even washers. They release with just a small flat head screwdriver to pop the head out. I'm adding another option for people to try - I really prefer them - some people may like the well nuts and there are many ways to get the job done.How are these better than well-nuts, which are much less expensive and have threads for more positive attachment?
I glued well-nuts to car so they won't fall out when screw is removed.
Installed, I pulled on them and they will not come out.
I would not use a well nut or snap type fastener to replace a bolt. It may work fine but with plastic and rubber you're dealing with materials that haven't nearly the tensile strength of steel.I had a thought the other day. Maybe you could use these to replace the two 13 mm bolts that hold up the diffuser. That'd go well with the 1/4 turn fastener kit.
1/4 turn kits are still out there! I scored a Lotus-specific kit from Dieselgeek (a VW tuner) a couple months back.Yep - that's on my list... I wish the 1/4 turn was still available...
