I'm not sure I am using the proper terminology, but I am referring to the rivets that hold the plastic faces of standup targets to the switches, metal brackets to ramps, etc...
I recently had to replace a ramp and it required me to reuse the old metal mounting bracket. I drilled out the rivets, but I had no way to reattach the rivets. I ended up putting screws in, which worked, but I'd prefer to use rivets.
I do see a few options out there, but what works best? Pros and Cons?
