# What is the minor diameter of thread?

## What is the minor diameter of thread?

The minor diameter is the lower extreme diameter of the thread. Major diameter minus minor diameter, divided by two, equals the height of the thread. The minor diameter of a nut is its inside diameter.

### What is minor diameter of external thread?

The minor diameter (root diameter) is the diameter of a cylinder that just touches the roots of an external thread. The crest of a thread is the top portion of a thread. The root is the lowest groove between the two flanks of the thread.

## How do you find the minor diameter of external threads?

The minor diameter can be determined by direct measurement on an optical comparator or by measuring the depth of the thread with a depth micrometer and subtracting twice the measured depth of thread from the major diameter.

What is the minor diameter of a 10-32 thread?

Which diameter is used for specifying a thread?

Inch sizes are specified using the nominal major diameter and the number of threads per inch. For example, a 3/8-16 (coarse) thread has a 3/8″ nominal major diameter and 16 threads per inch, while a 3/8-24 (fine) thread has the same nominal major diameter and 24 threads per inch.
