In a bolt designation, what does the pitch represent?

The pitch in a bolt designation refers specifically to the distance between adjacent threads measured along the axis of the bolt. It is an important parameter in bolt specifications because it determines how closely the threads are spaced, which affects the bolt's ability to create a secure connection when tightened. A finer pitch generally allows for more precise adjustments and a tighter fit, while a coarser pitch can mean quicker assembly and disassembly. Understanding the pitch is crucial for applications that require specific torque and load-bearing capabilities, as it directly influences the performance of the bolted joint.
