Pins for holding name plates on - what is their correct name?

[Mayhem]

Thanks guys. Actually I found a bucket full of chips when I dismantled the mill, so I won't need to make any for a while! I couldn't believe how much was inside the knee. Found them in some places that made me wonder how they got where they did! Been too hot to paint here, so will get the rest done once it cools down a little.

Edit: to fix a typo
