Put it, along with the documentation for whatever the thing is, and tape (packing tape works well) to the back of the thing. When it comes time to move or do something that requires the manual and/or tools, you have both the tools and documentation easily at hand and not lost in some junk drawer somewhere.
I have a couple of them saved, but I have sets of actual tools that include Allen wrenches. So, I don’t keep most of them. I do keep the instructions with the item, though.

Every 10th one you add to the drawer you get a prize.
