[Too Many Projects]

I believe the sockets are slightly too big too. I've had size issues with tail light sockets as well.
I've, also, run into this with other fasteners from China that are Imperial thread, but the shank of the bolt is undersized and the bolt will skip threads when attempting to tighten it. Then the next set of fasteners, the nut is under size and the bolt is too tight right from the start and I need to run a thread chaser thru the nut. Imperial threads, but incorrect sizing of the corresponding part.
