Screws larger than 10 are listed as fractions of an inch.
A 9 16 12 screw which is comparable in diameter and is also coarse has its threads spaced 0 083 inches which are farther apart so there will be fewer threads per unit of measure we used an inch in the table above.
For precision measuring we would recommend the use of digital vernier calipers and a thread gauge to measure thread pitch.
Coarse pitch threads are preferred and should be used whenever possible as stated in asme b1 13m.
