How are threads measured?
Steps
- Measure an inch-long portion of the threaded area. Grab a ruler and lay it along the bolt or screw.
- Count the number of threads in 1 inch.
- Measure the diameter and the length of the threaded area.
- Plug the information into a standard measurement.
How do I know what type of thread?
- Determine if the thread is straight (parallel) or tapered. The thread is tapered if the diameter increases or decreases.
- Measure the thread diameter.
- Determine the number of threads per inch (TPI) or the pitch (metric threads) with the thread gauge.
- Determine the thread standard.
How far does a pipe thread into a fitting?
If you are using 1/2-inch pipe, add 7/16 inch per end; and add 1/2 inch per end for 3/4-inch pipe. Therefore if you plan to use 3/4-inch pipe to join two fittings 36 inches apart, you would need a pipe 37 inches long (adding 1/2 inch on either end to allow for penetration into the fittings).
