8 0.125. 114.30. 4.500. View our handy online thread size tables to help you find all the information you need about the valve or pipe threads you are working with. Our tables cover thread size, threads per inch, pitch and thread diameter. We have thread tables for both British Standard Pipe (BSP) and National Pipe Thread (NPT).
DrillSize. 3/8”. 37/64”. ½”. 23/32”. ¾”. 59/64”. As you can see from the chart, every tap size has a different drill size. If you do not use the correct drill size, you run the risk of making holes that are too large or too small which can ruin the project.ISO261 specifies a detailed list of preferred combinations of outer diameter and pitch for ISO metric screw threads. The 1st choice column follows the R10 series from ISO 3, while the 2nd choice column is rounded off values from the R20 series from ISO 3. ISO 262 specifies a shorter list of thread dimensions - a subset of ISO 261.

BSPT& BSPP Threads Dimensions. Thread size refers to the nominal bore of the pipe. Subtract approx. 1/4″ (6mm) from thread diameter measurement for nominal pipe size. Pitch is Threads Per Inch (TPI).

306 2019 Page 1-2 MEASURING TAPER THREADS R, Rc & NPT Nominal pitch diameter for taper threads is given at a specified distance from the end of the pipe and the larger the taper thread diameter (pipe diameter) the greater the distance. e.g. for R & Rc ½” the distance is 8.2mm, 1” is 10.4mm and 2” is 15.9mm.
