They sent me a used non-spec nut.

Would Not Recommend

I don’t even know where you would buy this. It’s half the thickness of the standard nut, and has a beveled edge on the back side of it. I bought four for my brush cutter. Three were standard and the fourth was this. You can see where someone took a star wrench to it and stripped the top half off, that wasn’t me. You’re selling salvage nuts now Lowes? I should’ve just gone to the store myself.
