Back in the old days of changing your plates out every year, it was prudent to use hardware that didn't rust together. But now, license plates here only get replaced about every twenty years, and you just put a renewal sticker in the corner each year. Well, I'm finally getting my first set of new plates after many years, and had a question for you guys. I want to make it difficult to steal them. (I bought some nylon bolts and nuts for this purpose many years ago and never used them because of the shift to stickers. But now.... I was going to use them but then I thought, why make it easier for someone to steal my plates?) I asked this question on another forum and got suggestions like pop rivets and torx head screws. Does anyone have any thoughts on this strange topic? What do y'all use?
