The unified thread standard has three distinct variances called Unified Coarse Thread (UNC), Unified Fine Thread (UNF), and Unified Extra Fine Thread (UNEF). The difference between the three is the amount of threads per inch. For example, a 1 inch fastener size in UNC has 8 TPI, in UNF 12 TPI, and 20 TPI in UNEF).

BSPP Go Plug Gage - G1/8. BSPP is also known as British Standard Pipe Parallel. This gage checks the internal parallel threads that do not create pressure-tight joints. They utilize GO/NOGO members which allows the user to accurately check the tolerance of the thread profile. The standard of compliance for this gage is ISO 228-1 and ISO 228-2.

It is marked as G, which represents cylindrical thread. The national standard can be found in GB/T7307. In addition, 1/4, 1/2 and 1/8 in thread refer to the diameter of thread size, and the units used are inch. Insiders usually use the points to refer to the thread size, one inch is equal to 8 points, 1/4 inch is 2 points, and so on.

Pipe thread sizes are described much as bolt sizes are, although the shapes are different. For example, "½-14 NPT" identifies a pipe thread with a nominal inside diameter of ½ inch and 14 threads to the inch, made according to the NPT standard.
