I typically throw them in the junk drawer. That is pretty much what they are, and if I ever need to tighten something it's there. If I can get one use out of them before bending them up, I;m generally doing good.
These, and old worn out tools go into a 2.5 gallon bucket. The bucket sits on an out of the way shelf. I also put a bucket of iron in the bottom of my ballast box with a concrete cap.
Yeah, usually throw them in a misc drawer but sometimes I cut them off straight so I can chuck them in a drill/driver for fast assembly knowing I have plenty of 'real' ones.
Like LD1 said, they're so cheaply made that they're not usually worth keeping. I just threw away a bunch of that kind of junk. I don't think there was anything that I didn't have a "real" tool duplicate for.
On other things like tools I replace before they're worn out, gifts I don't really need, etc. I lay back and give to my son or son-in-law. Doubt they need 175 cheap allen wrenches, but they do appreciate occasional tools.
does, "they dont make it out of the package" count? i generally dont bother with them because they are so cheep, Ill use my own (quality) tools to do the assembly.
