Helix Angle for Single Threaded Screw Calculator

Calculate Helix Angle





Formula

The formula to calculate the Helix Angle is:

\[ \psi = \tan^{-1}\left(\frac{P_{\text{screw}}}{\pi \cdot d}\right) \]

Definition

Helix Angle is the angle between any helix and an axial line on its right, circular cylinder, or cone.

Example Calculation

Let's assume the following values:

Using the formula:

\[ \psi = \tan^{-1}\left(\frac{5}{\pi \cdot 0.06}\right) \approx 1.53311505935313 \text{ radians} \]
