1. What Is The Torque Formula?

The torque formula T = K × F × D calculates the torque required to tighten a bolt, where T is the torque in Newton-meters (Nm), K is the torque coefficient (dimensionless), F is the force in Newtons (N), and D is the diameter in meters (m).

2. How Does The Calculator Work?

The calculator uses the torque formula:

Where:

• \( T \) — Torque (Nm)
• \( K \) — Torque coefficient (dimensionless)
• \( F \) — Force (N)
• \( D \) — Diameter (m)

Explanation: The formula calculates the rotational force needed to properly tighten a bolt, accounting for friction and other factors through the torque coefficient.

3. Importance Of Torque Calculation

Details: Proper torque calculation is essential for ensuring bolt integrity, preventing under-tightening (which can lead to loosening) and over-tightening (which can cause bolt failure).

4. Using The Calculator

Tips: Enter the torque coefficient (typically between 0.15-0.25 for metric bolts), the force in Newtons, and the diameter in meters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical torque coefficient value?
A: For metric bolts, the torque coefficient typically ranges from 0.15 to 0.25, depending on the bolt material, lubrication, and thread condition.

Q2: How do I convert diameter from mm to m?
A: Divide the millimeter value by 1000. For example, 10mm = 0.01m.

Q3: Why is proper torque important?
A: Proper torque ensures joint integrity, prevents leaks, and maintains the clamping force needed for the application.

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

Q5: Can this formula be used for imperial units?
A: Yes, but units must be consistent. For imperial units, torque is in lb-ft, force in pounds, and diameter in feet.
