What is the depth of a thread?

Depth of Thread: The distance between the crest and the base of the thread measured normal to the axis. Number of Threads: The number of threads in one inch of length. Length of Engagement: The length of contact between two mated threaded parts measured axially.

How do you calculate BSP thread?

To find the thread size:

1. 1) Measure the O.D (outer diameter) of the BSP thread.
2. 2) Take the O.D measurement (in inches) and subtract 1/4 inch (. 25”).
3. 1) Multiply 3.5 by 4 to get 14. This is the number of threads per inch.
4. 2) Combine the thread size with the number of threads per inch and refer to.

When to use parallel or tapered BSPT thread?

BSPT thread used where pressure-tightness is made through the mating of two threads together. In International standards require all Female thread is parallel and male thread is tapered. Female thread can also be tapered but this is not common.
