Determination - Thread Types G or R or BSP G or R (Whitworth) or BSP (British Standard Pipe) Thread Cylindrical threads which are mainly used in countries with imperial system. The size of e. g. R 3/4" does not stand for a diameter. Thus the corresponding size has to be determined according to charts.

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).

Threads on parallel fasteners use a cylindrical blank having an outside diameter between the major and minor diameters of the finished thread. A bar is rotated between hardened steel dies bearing the reverse thread form. The die threads penetrate the blank surface to form the thread roots and displace material radially outward to form the crests.

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

We have compiled a simple step-by-step guide to help you identify your thread type. In addition, we'll cover some of the most common port thread types including NPT/NPTF, BSPP (also known as G), BSPT, PT, Metric (M) and SAE. You'll need a couple tools on hand to make the process easier, but a straight steel ruler may work as well.
