Are BSP and G threads the same?
Is G thread the same as BSPP? The two types of thread are the same parallel straight. BSPP is the British Standard Pipe Parallel thread and it is also denoted by the letter G (ISO standard). Therefore, BSPP is the same as G.
What is the difference between R and G thread?
BSP distinguishes between two types of threads. These are parallel threads (BSPP), which have a constant diameter, which are known a G threads, and taper threads (BSPT), whose diameter increases or decreases along the length of the thread, known as R threads.
Is M8 same as 8mm?
The defined diameter of metric bolts is actually slightly larger than the actual diameter of the bolt shaft. So an M8 bolt would have a shaft diameter that’s slightly under 8mm which means that the bolt should fit through an 8mm hole.
