Technical Wire wheel lug nuts

Is there a specific lug nut for the factory 1935 ford 16x 5.5 wire wheels or special pitch on it are they the 1/2 x 20 standard ford ?

 

standard 1/2 x20, large 13/16" wrench size. original nuts have the bottom 2-3 threads missing and drilled larger to clear the stud shank. Many aftermarket nuts are threaded all the way, so check to make sure you are actually tightening the wheel, and not just run out of threads
