Random question, I know, but any help would be appreciated.
I have this compass cutter
and I've noticed that, with a bit of modification, the two bolts that hold the blade and the point to the frame would be almost perfect as a thing to use to press down a tactile switch. I've been running around google and eBay all day, and I have just run out of ideas as to what on earth is the proper type of name for this kind of bolt. Here are some pictures of the things
worse comes to the worst, I'll just use the ones I've got, even if it means getting another circle cutter, but I'd prefer not to. If anyone has any ideas, I'm all ears.
