Calculate Fastener Torque





Formula

To calculate the Fastener Torque (\(Tf\)):

\[ Tf = \frac{D \times P \times K}{12} \]

What is Fastener Torque?

Fastener torque is the amount of rotational force applied to a fastener, such as a bolt or screw, to achieve the desired clamp load. It is a critical parameter in ensuring the proper assembly and performance of mechanical systems.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ Tf = \frac{0.5 \times 1000 \times 0.2}{12} = 8.33 \text{ lbf-ft} \]

The Fastener Torque is 8.33 lbf-ft.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ Tf = \frac{1 \times 2000 \times 0.15}{12} = 25 \text{ lbf-ft} \]

The Fastener Torque is 25 lbf-ft.
