/diy/ - Do It Yourself

So I ordered some light switch locks from amazon, 4 sets of 4, so that the lights in the common/egress hallways in my office/shop building can't be turned off. However when I received the package, it had only 3 sets of the light switch locks and a bag with a few sets of this hardware (in the pic) in it. Oddly, the label on the bag these came in is a label for the light switch locks I ordered. So obviously it's a labeling error and a warehouse monkey just threw it in despite it clearly not being the correct item. Fine, whatever. What I'm wondering is what the hell these are. I was just going to throw them away because it's not worth trying to return this shit, but I figured I'd try to find out what they are first in case they may be useful. There are no part numbers or anything like that on the bag or on the parts themselves to hint at what they are. Any ideas?
