What is formula of checking pitch of bolt?

The pitch of a bolt is the distance between threads measured along the bolt's axis. It can be calculated using the formula: Pitch = Distance between two adjacent threads. For metric bolts, the pitch is typically given in millimeters, while for imperial bolts, it is often measured in threads per inch (TPI). To convert TPI to pitch, use the formula: Pitch (inches) = 1 / TPI.
