Thread ChartsPitchMajor DiameterMinor DiameterGage LengthTradeSizeThreadsper NPTNPT stands for National Pipe Thread and is an American standard thread. It may also be reffered to asMPT , MNPT or NPT (M) for male external threads and FPT, FNPT or NPT(F) for female interal threads.A thread sealant must always be used to achieve a leak free seal (except for NPTF). It is also based onTrade Size rather than actual diameter (similar to BSP in this regard).Both threads have the same pitch, angle (60 degrees) and shape (flat peaks and valleys).Trade Size1/81/43/81/23/411¼1½22½34Threads perinch271818141411 ½11 ½11 ½11 .208782.208783.175003.175003.17500Major Diameter 32.87573.033.50088.904.500114.30
BSP vs NPTNPT threads are common in the United States and a few other countries, BSP threads are widely used inmany other countries. BSPT -British Standard Pipe TaperBSPP -British Standard Pipe ParallelNPT -National Pipe TaperNPS -National Pipe StraightWhile the actual specified outside diameters of American National Pipe differ slightly from those ofBritish Standard Pipe, either thread may reliably be cut onto a pipe of its respective trade size. BSPTequivalent is NPT and BSPP’s equivalent is NPS.Never swap threads if it is a high pressure application.NPT/NPS and BSP threads are not compatible due to the differences in their thread forms, and not justthe fact that most sizes have a different pitch. NPT/NPS threads have a 60 angle and have flattenedpeaks and valleys (Sellers thread form) where as BSP threads have a 55 angle and have rounded peaksand valleys (Whitworth thread form).NPT and BSP thread pitches (threads per inch) are listed below. To determine pitch, use a thread gauge orcount the number of threads that fall into a 1" span.Trade Size1/81/43/81/2¾11¼1½22½33½456Pitch (Threads per Inch)NPT/NPSBSP2728181918191414141411 ½1111 ½1111 ½1111 ½11811811811811811811

The shank is the part of the drill bit grasped by the chuck of a drill. The cutting edges of the drill bit are at one end, and the shank is at the other. Drill bits come in standard sizes, described in the drill bit sizes article. A comprehensive drill bit and tap size chart lists metric and imperial sized drill bits alongside the required .

roll threaded should have a UNR thread because thread rolling dies with rounded crests are now the standard method for manufacturing most threads. UNJ Threads UNJ thread is a thread form having root radius limits of 0.150 to 0.180 times the thread pitch. With these enlarged radii, minor diameters of external thread increase and intrude beyond .
