Formula for minor diameter of thread
WebThe minor diameter is the diameter of an imaginary cylinder that touches the smallest diameter of a thread. It depends on the pitch and the thread’s angle. Minor Diameter … WebTPI stands for Threads Per Inch, which means the total number of threads per inch measured along the length of a fastener. TPI is used only with American fasteners. Metric Fasteners use a thread Pitch. In general, smaller fasteners have finer threads, so the thread count is higher. Thread Pitch
