No, not the nut behind the wrench!! In a quick look around, I haven't found a description of the nut used on the spring center bolt--square or hex?
And I would assume that after tightening the nut, one should peen the end of the bolt to prevent loosening??
BTW, the bolts are works of art--many thanks to Bob & others who made this happen!!

I think it might be square, that's what the Model A used. After the nut is installed cinched down and the excess bolt is cut off the end should be peened over to keep the nut from backing off. The thing about a square nut is it has only four corners to help lock to the spring leaf, the hex is more round and has less surface area. :-)

The front spring bolt nut is 19/32" square x 5/16" thick. The thread is 5/16" x 18 tpi.

The rear nut is 9/16" square x 3/8" thick. It is threaded 3/8 x 16 tpi.

Hope this helps.
