Thread sizes for coarse and fine pitch thread were created using the standard sizes from ASME B1.13M. Still, there are some oddly shaped bolts out there. It happens, its frustrating, its time-consuming, I get it. The greater the pitch on metric fasteners, the more distance between threads. This calculation and conversion factor is valid for either metric or standard bolt sizes. A conversion table would be handy if you often convert between these two systems. Finding the right type and specifications will hold materials together nicely. For example, a #0 gauge is 1/16 inch in diameter. For round-headed ones, measure from the tip to the bottom of the head.
