Tensile strength values are based on 60,000 psi. The standard metric fastener thread series for general purpose threaded components is the M thread profile and the coarse pitch thread series. The first number listed is the size of thread, the second number is the threads per inch. 50 Pitch 10. We really only need to find the pitch diameter to solve the formula. from thread data chart for minor diameter compair major diameter row = 9. 4 threads per inch. Thread series cover designations of diameter/pitch combinations that are measured by the number of threads per inch (TPI) applied to a single diameter. ) If you normally work with inch fasteners, pitch can be a little confusing—pitch is the distance between adjacent threads.

This N-AN series through size AN-26 meets the many exacting requirements for good operation of tapered roller bearings but series PN in all sizes meets specifications for the safest and best. 3B #0 - 80 UNF. The pitch of the thread determines the diameter of the contact points required for taking measurements. The taper rate for all NPT threads is 1⁄16 (3⁄4 inch per foot) measured by the change of diameter (of the pipe thread) over distance. All new designs could best use the 12 and 8 pitch AN series of threads for the greatest assurance of long term compatibility and future availability. threads (inches).
