Depth = the pitch X cos of 30° This gives the depth of sharp threads. Actual threads will be different accordingly to the radii at the root and crest. The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, never let suggestions go unsaid nor fail to listen to them.

Pitch X the cos of 30° is the depth of sharp threads (point to point). To figure for actual root and crest radii of your thread you must calculate the tangents of the radii you use into the formulas.
