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 ...
See Tap Drill Sizes for NPT Pipe Threads . Note b: Reference dimension. - NPT Thread taper angle = 1/16 taper = 1 deg. 47 min = 0.75 in./ft . - The angle between the sides of the thread is 60 deg. - Thread Designation: The nominal pipe size, number of threads per inch and the thread series symbol in sequence.

UNC thread chart including major diameter, pitch diameter and minor diameter dimensions of UNC screw threads according to ASME B1.1 standard.
However, ASTM A193 is one of two exceptions (A320 being the other) in which 8UN threads (8 threads per inch) are standard for fasteners larger than 1″ diameter unless otherwise specified. With that said, A193 bolts can be ordered with UNC threads if that is specified when they are ordered. If a thread pitch is not specified, most fastener ...

Metric internal thread dimensions chart according to ASME B1.13M "Metric Screw Threads: M Profile" standard. Minor diameter, pitch diameter and major diameter are given dimensions in the internal thread chart. All dimensions are in millimeters. Internal thread (or nut thread) is a term to describe all internal threads in ISO metric thread ...
Thread Pitch Chart. Thread series displays various diameter/pitch combinations that are measured by the number of threads per inch (TPI), applied to a single diameter. Includes both standard screw and metric screw thread. Nominal Dia. (mil.) This chart displays various diameter/pitch combinations, as measured by threads per inch (TPI).
