## How do you calculate minor diameter of a thread?

According to page 1528 of The Machinery’s Handbook (29th Ed.), that formula is given as A_S=(π/4)*((d_m+d_p)/2)^2 where the pitch diameter is d_p=d−0.649519×P, and the minor diameter is d_m=d−1.299038×P.

**What is minor diameter of external thread?**

root diameter

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. The flanks of a thread are the sides that connect the crest and the root.

### What is the effective diameter of thread?

The pitch diameter (often called the effective diameter) of a parallel thread is the diameter of the imaginary co-axial cylinder which intersects the surface of the thread in such a manner that the intercept on a generator of the cylinder, between the points where it meets the opposite flanks of a thread groove, is equal to half the nominal pitch of the thread. The major diameter of a thread is the diameter of the imaginary co-axial cylinder that just touches the crest of an external thread

### How do you calculate thread pitch diameter?

To calculate the pitch diameter, one must imagine a cylinder whose diameter exists at the point where the thread groove width and the thread crest width are both equal to one another and equal to half the nominal pitch of the thread. The diameter of this imagined cylinder is the pitch diameter.

**What is the diameter of a 6 – 32 screw?**

The #6-32 UNC is a UTS screw specifying a major thread diameter of #6 which is defined as 0.1380 inches (3.51 mm); and 32 tpi (threads per inch) which equates to a thread pitch of 0.031250 inches (0.7938 mm).

## What are the dimensions of a thread?

Dimensions of a Thread. The length of a thread is 54 inches. This term is basically used to measure cotton yarn. It goes together with other significant aspects of cotton count such as the term ‘tex,’ which specifically refers to the weight of a kilometer of yarn in grams.
