Thread pitch

[banjaxed]

On the Skywatcher stainless steel tripod with 3/8" thread, does anyone know what the actual pitch is.

I think it might be UNC or UNF but can't find any info.

The 3/8" thread is 3/8-16 UNC so 16 TPI. The 1/4" thread is 1/4-20 UNC.

Thank you very much for the info Alan, it never ceases to amaze me how much combined knowledge there is on this site.
