Therefore, thread standards can be used to help define end connection standards . Pitch For all metric screw threads, pitch refers to 1/8. ISO 7/1.

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).

In this video we create a BSP Thread Profile using the Sketch Equation through SolidWorks. The Pitch of the thread is 1/14 inch. Cylindrical threads according to ISO 228-1, identified with a letter G. They also correspond to BSP or more precisely to BSPP designation (P stands for Parallel). 1 BSP X 25.4MM (21MM BORE) 316 HOSE TAIL (NB25) BSPHT6025. In Stock.

Thread pitch is the distance between the threads and is used for metric fasteners. G-threads have a parallel shape in accordance with the DIN-EN-ISO 228-1 standard with flank angle 55 o.

Step 3 - Pitch Size. The next step in identifying your thread type is to determine the pitch size. A thread's pitch size is the number of threads per inch or the distance between threads on metric thread types. While a ruler could be used to calculate the pitch size, a pitch gauge is highly recommended as pitch sizes can be very similar.

Example: 1/8 NPT thread = 1/8 NPT Example: metric thread diameter 7 with a pitch of 1 mm = M7x1 BSP parallel: G followed by the designation.

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.

The most common types of Whitworth thread are: BSPP (G) – British Standard Pipe Parallel. BSPT (R/Rp) – British Standard Tapered Pipe, for pipes and tapered thread. An appropriate

NPT/NPS threads have a 60° angle and have flattened peaks and valleys (Sellers thread form) where as BSP threads have a 55° angle and have rounded peaks and valleys (Whitworth thread form). NPT and BSP thread pitches (threads per inch) are listed below. To determine pitch, use a thread gauge or count the number of threads that fall into a 1
