1. What is the Clamp Load From Torque Calculation?

The clamp load calculation determines the axial force generated when torque is applied to a fastener. This is essential in engineering and mechanical applications to ensure proper joint integrity and prevent failures.

2. How Does the Calculator Work?

The calculator uses the clamp load formula:

Where:

• \( Torque \) — Applied torque (N m)
• \( K \) — Torque coefficient (dimensionless factor)
• \( D \) — Nominal diameter (m)

Explanation: The formula calculates the axial clamping force generated by a given torque value, considering the torque coefficient and fastener diameter.

3. Importance of Clamp Load Calculation

Details: Accurate clamp load calculation is crucial for proper bolt tensioning, joint integrity, preventing loosening, and ensuring safety in mechanical assemblies.

4. Using the Calculator

Tips: Enter torque in Newton meters, torque coefficient K, and diameter in meters. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the torque coefficient (K)?
A: The torque coefficient is a dimensionless factor that accounts for friction and other losses in the fastener system. Typical values range from 0.15 to 0.30.

Q2: Why is clamp load important in bolted joints?
A: Proper clamp load ensures joint integrity, prevents loosening under vibration, and maintains sealing pressure in gasketed joints.

Q3: How does diameter affect clamp load?
A: Larger diameters require more torque to achieve the same clamp load, as the relationship is inversely proportional.

Q4: What factors affect the torque coefficient K?
A: Surface finish, lubrication, thread pitch, and material properties all influence the torque coefficient value.

Q5: When should this calculation be used?
A: This calculation is essential in mechanical design, automotive engineering, aerospace applications, and any scenario where proper bolt tensioning is critical.
