Fender strut bolt pitch size?

[Dave Weaver]

I am getting everything organized to install a hitch on my Interstate and trying to acquire all the hardware before I tear into it.  I am getting metal and nylon bushings, carriage bolts, hex head bolts, all thread, etc. so I can go whichever directtion I feel.  I see the bolts are listed as 8mm and 10mm and it even shows the stock length, but not the pitch size.  I can buy 1.0, 1.25, or 1.5 pitch in bolts and want to know which size works with the stock square nuts in fender.  Thanks, 

Dave

The 8 & 10 mm bolts both have a 1.25 pitch. The 10 mm is a fine thread.
