1. What is the Thread Torque To Force Formula?

The Thread Torque To Force formula calculates the axial force generated from applied torque in threaded connections. It considers thread efficiency, torque input, and thread pitch to determine the resulting force output.

2. How Does the Calculator Work?

The calculator uses the Thread Torque To Force formula:

Where:

• \( F \) — Force (N)
• \( eff \) — Thread efficiency (dimensionless)
• \( T \) — Torque (Nm)
• \( pitch \) — Thread pitch (m)

Explanation: The formula converts rotational torque into linear force based on thread geometry and efficiency factors.

3. Importance of Force Calculation

Details: Accurate force calculation is crucial for proper bolt tensioning, joint integrity assessment, and preventing thread failure in mechanical assemblies.

4. Using the Calculator

Tips: Enter thread efficiency (typically 0.2-0.4 for standard threads), torque in Newton-meters, and pitch in meters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is typical thread efficiency?
A: Standard thread efficiency ranges from 0.2 to 0.4, depending on thread type, lubrication, and surface conditions.

Q2: How does pitch affect the force output?
A: Smaller pitch values result in higher force output for the same torque input, as the mechanical advantage increases.

Q3: When should this calculation be used?
A: This calculation is essential for bolt tensioning applications, threaded fastener design, and mechanical joint analysis.

Q4: Are there limitations to this formula?
A: The formula assumes ideal conditions and may need adjustment for friction variations, thread wear, or non-standard thread forms.

Q5: How accurate is this calculation?
A: Accuracy depends on precise efficiency values. For critical applications, experimental verification is recommended.
