You'd be surprised as to how much you would use them. You can buy knobs through different places like travers, Enco and such. A lot of places will call them "Quick Change Knobs" and they come in all different sizes from #10 on up. I use them on the belt covers of my 6' mower deck to make taking the covers on and off quicker.
