National Standard Taper Pipe Threads Size NPT Chart - Includes both External and internal Pipe Thread Data. The taper rate for all NPT threads is 116 (34 inch per foot) measured by the change of diameter (of the pipe thread) over distance.
· Thread and End Connection Identification (Steps 1 to 5) You have a male fitting and you need to identify its thread . Step 1: Determine if the thread is tapered or straight (parallel). You find that the thread is straight . Step 2: Measure the thread diameter. You find the thread diameter to be 0 .430 in . Step 3: Determine the thread pitch. a .

Thread Pitch. Thread pitch is the term used to calculate the difference between two threads. For metric fasteners, thread pitch is used in place of TPI. The distance is also measured in millimeters. To measure thread pitch, use a caliper and measure from the peak of one thread to the next. M2 x .4 x 5M
NPT/NPS threads have a 60° angle and have flattened peaks and valleys (Sellers thread form) where as BSP threads have a 55° angle and have rounded peaks and valleys (Whitworth thread form). NPT and BSP thread pitches (threads per inch) are listed below. To determine pitch, use a thread gauge or count the number of threads that fall into a 1

· Step 3 – Pitch Size. The next step in identifying your thread type is to determine the pitch size. A thread’s pitch size is the number of threads per inch or the distance between threads on metric thread types. While a ruler could be used to calculate the pitch size, a pitch gauge is highly recommended as pitch sizes can be very similar.
Each AN size number has its own standard thread size [see column three of the chart]. These are the same thread sizes that have been used in aircraft and industrial applications for many years. For some odd reason, the automotive industry wants to make AN fittings sound like something special.

Unified screw threads and tolerances calculator was developed to calculate basic major, minor and pitch diameters of the external (bolt) and internal (nut) inch thread according to ASME B1.1-2003 standard. In addition to basic size calculations, limits of sizes calculations of different tolerance classes can be done according to same standard.
· 184.108.40.206 Special UNJ Thread Data: Dimensions for threads of special diameter-pitch combinations shall be computed from the formulas in Table 9. 3.3.2 External threads: External threads shall be of Unified form, in accordance with ASME B1.1 (Class 3A), altered at the root so that the flanks of the adjacent threads are joined by one continuous
Thread Pitch Chart. Thread series cover designations of diameter/pitch combinations that are measured by the number of threads per inch (TPI) applied to a single diameter. Coarse Thread Series (UNC/UNRC) is the most common designation for general application bolts and nuts. Coarse thread is beneficial, because they are less likely to cross
