Thread Pitch Chart Thread Pitch ChartThread series cover designations of diameter/pitch combinations that are measured by the number of threads per inch (TPI) applied to a single diameter. Coarse Thread Series (UNC/UNRC) is the most common designation for general application bolts and nuts. Coars...

Use a thread pitch gauge to determine the number of threads per inch or the distance between threads in metric connections. Place the gauge on the threads until the fit is snug, and then match the measurements to the accompanying chart. Video Resources and Guides Thread Pitch and Size- Courte...
As an example, a hole is required for a 1/4″ x 20 threads per inch. There is a simple conversion for thread per inch into pitch. The pitch (distance from crest to crest) is the inverse of the threads per inch. For 20 threads per inch, 1/20 is equal to 0.05-inch pitch. The ...
Not all families allows custom thread sizes, but many do. You’ll need to enter a Nominal Size (also known as the Basic Major Diameter) and either TPI (Threads Per Inch) or Pitch (many metric Families use pitch) for your custom thread size. Given your desired Tolerance Class, GW Thread...
a 4G5G bolt would have a grade 4 pitch internal thread and a grade 4 crest internal thread. When the pitch and crest grades are the same, the notation is simplified; a 4G4G bolt would be labeled 4G instead. Threads with higher tolerance install quicker and are better-suited to accommodate...
