Well, I suppose I should be the first to admit. I'm a bubba. There, I said it.
I've got a stud and a wingnut on my Handi Rifle, so that I don't need a tool to disassemble it. I may have unintentionally lost the proper screw, I may have it in a drawer somewhere, but for the purpose I intend the bubba'd replacement works better than the original.
Just saying, it's an option if you can find the correct diameter and threading. Maybe not permanently, but it can't hurt to find out that Home Depot carries a twenty cent alternative.
