How about using a wingnut instead of a nut?


Back at home, I looked up some assortment kits for wingnuts at Amazon and found one kit that looks promising...
That comes out to under 7 cents per wingnut. Of course, I would be buying a lot more wingnuts than I currently need, but I like the mix of both standard and metric wingnuts in that assortment set in a plastic storage case. Probably the last wingnut kit I would ever have to buy. I decided to put that item on my Amazon wish list.
I still want to look around at other options, like maybe Harbor Freight. I have purchased a number of assortment kits from them on other stuff, usually when they have a good sale or coupons.
Might even find a wingnut laying around the garage now that I am cleaning up stuff and getting things more organized. I never throw stuff like that away, but it's like going on a treasure hunt with nothing much organized. Just jars full of miscellaneous hardware to look through.
