Long story short- Need to buy a nut asap and I'm at work so i cant measure it. I'd orderd one from JP monday, and it said in stock, looked up tracking today and now it says it wont ship for 11-14 days, no good. So i need to order one from Mcmaster or pick one up from the hardware store today. Anyone know the thread size? Thanks guys. Googling I can only find the socket size needed, not the actual thread size.
