How do you determine the pitch of a screw?

The pitch is the distance between the threads; you can determine this number by measuring the number of threads per inch (or centimeter) on the screw, then divide one by the number of threads (pitch = 1 ÷ number of threads per inch or cm). For example, if a screw has eight threads per inch, the pitch is 1/8.
