I was trying to clean the terminals on my battery and dropped one of the nuts. I looked and it has apparently disappeared into a black hole. I assume I can just go too Lowe's and buy a nut of the appropriate size. The nut I lost is the one that tightens down the terminal. Does anyone know what the thread size would be? I'll attach a pic of which nut I lost, just to be certain.

 

Did you ever figure it out? I'm looking at other posts too but yours was the exact one I needed.

 

Take the one off the other side and go to store and match it ???

 

They're different sizes but I bought a couple so ill just see which one fits
