My PSA is really this:
Don't be afraid to buy generic, so long as the spec matches
Buy a bag of them.
My car started making funny noises a couple of weeks ago, and a short visit under the car identified the culprit: more than one piece of the undercover was flapping. I've taken that cover (and others) off more than a few times, and I tend to either break or lose a push-pin or two each time. It adds up
First I tried to buy a couple of pins at Lowes. They cost $1 each, and they ended up being the wrong size. Then I went looking online and found the above vendor. I honestly doubt my purchase was anything special, it seems like buying in bulk 8 mm push pins that are Nissan LEAF compatible is enough to know to make a good purchase. I bought these, link provided mostly for the correct spec to look for:
100 push pins for ~ $7
And I have to say, buying the right pin is a joy. The base goes easily and snugly into the hole, and then the pin goes in with a click. End of drama. I've gone from being a push-pin critic to a happy camper now that they are cheap, available, and very well engineered.
