It is also used to refer to the bottom surface joining the sides of two adjacent threads. On external threads, the roots are usually rounded. The diameter of a thread at an imaginary point where the width of the groove and the width of the thread are equal. The diameter equal to the external diameter of the threads. The diameter of a screw thread measured from the thread pitch line on one side to the thread pitch line on the opposite side.įor fractional screw threads and pipe threads: pitch is the number of threads per one inch.įor metric screw threads: pitch is the distance between adjacent threads. Thread size is the actual measurement of the threads and the threads per inch (TPI).
