Home depot USED to, but it looks like they took the nylon nuts and bolts out of stock, as they are no longer there. As I said, I was just in Lowes and held the proper bolt in my hand. It was cheap too. Lowes pretty much stocks the same stuff most everywhere too. I have been in a LOT of them. Where exactly are you looking in Lowes? They have a line of speciality bolt/hardware cabinets in the hardware section, and the nylon stuff is almost at the end of it. The ones I saw are the right diameter and more than long enough to hold your coil. Have another look, and DONT ask an associate. Most of em cant find their arse with both hands. (although there is an occasional one that actually knows something) Look yourself.
