1. What is M10 Bolt Torque Calculation?

The M10 bolt torque calculation determines the appropriate tightening torque for M10 bolts based on the desired preload. Proper torque ensures joint integrity without overstressing the bolt.

2. How Does the Calculator Work?

The calculator uses the torque equation:

\[ Torque = 0.2 \times Preload \times 10 / 1000 \]

Where:

\( 0.2 \) — Friction coefficient (typical for steel)
\( Preload \) — Desired bolt preload in Newtons
\( 10 \) — Nominal diameter of M10 bolt in mm
\( 1000 \) — Conversion factor from mm to m

Explanation: The equation accounts for friction and bolt size to convert preload force to required torque.

3. Importance of Proper Torque

Details: Correct torque application is crucial for maintaining joint integrity, preventing loosening, and avoiding bolt failure from over-tightening.

4. Using the Calculator

Tips: Enter the desired preload in Newtons. The value must be positive. The calculator will output the required torque in Newton-meters (Nm).

5. Frequently Asked Questions (FAQ)

Q1: Why is torque important for bolts?
A: Proper torque ensures the bolt develops the correct clamping force without being overstressed.

Q2: What factors affect torque requirements?
A: Surface finish, lubrication, thread condition, and material properties all influence the required torque.

Q3: Is this calculation valid for other bolt sizes?
A: No, this is specific to M10 bolts. Different sizes require different calculations.

Q4: What's a typical preload for M10 bolts?
A: Preload depends on the bolt grade and application, but common values range from 10-40 kN for standard M10 bolts.

Q5: Should I use this for critical applications?
A: For critical applications, consult engineering specifications or perform actual testing.
