g thread chart

ANSI/ ASME INTERNAL Screw Thread Size Chart. All units are in inches. Unified Screw Threads per. ANSI/ASME B1.1-1989 (R2001), R2001) Nomenclature, are used. Acceptability criteria are described in ANSI/ASME B1.3M-1992 (R2001). Note: This screw chart is not comprehensive of all available standard threads as provided by the standard.

There are two types of BSP threads; - BSPP - male thread are both (also known as G) - BSPT - thread is parallel and the male thread is tapered (also know as R/Rp) (the thread can also be tapered it is then Rc, these are fairly rare to find).

Metric Thread Tolerances. The tolerances TD for internal threads and Td for external threads is derived from the class. The approximate tolerances can be calculated according to the below

per inch, while a 1/4-28 (UNF fine) thread has the same nominal major diameter but 28 threads per inch. Metric thread specifications are different because the thread pitch is defined by the distance between each thread in mm instead of threads per inch. For example, an M12x1.75 (coarse) thread has a 1.75mm pitch, while an M12x1.50 (fine) thread
