Thread Wire Constant Calculator

Pitch (threads per inch):

Wire Diameter (inches):

Constant:

The thread wire constant is a critical parameter used in engineering and manufacturing processes, especially in industries involving threaded fasteners. It helps determine the relationship between the pitch of threads and the diameter of the wire used.

Formula

The thread wire constant (CCC) can be calculated using the formula:

C=1P−(D×0.86603)C = \frac{1}{P} – (D \times 0.86603)C=P1​−(D×0.86603)

where:

  • CCC is the thread wire constant
  • PPP is the pitch (threads per inch)
  • DDD is the wire diameter (inches)

How to Use

Using the Thread Wire Constant Calculator is straightforward:

  1. Enter the pitch of the threads in threads per inch.
  2. Enter the diameter of the wire used in inches.
  3. Click the “Calculate” button.
  4. The thread wire constant will be displayed.

Example

Suppose we have threads with a pitch of 20 threads per inch and a wire diameter of 0.1 inches. Using the calculator:

  1. Enter 20 in the pitch field.
  2. Enter 0.1 in the wire diameter field.
  3. Click “Calculate.”
  4. The thread wire constant is calculated as approximately 0.974.
