How much torque does a M3 screw need?
Torque Specifications
| Size | Min | Max |
|---|---|---|
| M3 | 10 | 1.4 |
| M4 | 23 | 3.2 |
| M5 | 46 | 6.3 |
| M6 | 79 | 10.9 |
How do you calculate torque of a screw?
The widely recognized engineering formula, T= K x D x P (to be explained later in this article), was used to provide the chart’s values, but it must be understood that every bolted joint is unique and the optimum tightening torque should be determined for each application by careful experimentation.
What is the torque for a M20 bolt?

What is the torque setting for a 10mm bolt?
Metric Recommended Bolt Torque
| Bolt Diameter (mm) | Recommended Torque (Nm) | |
|---|---|---|
| Class 8.8 | Class 10.9 | |

What is torque value Nm?
Torque is a measure of how much twisting is applied to a fastener. The units used to measure torque are in the form of force times length. The metric (SI) unit of torque is the newton metre (Nm). In inch units, torque is usually measured as Lb-Ft (pounds feet) or Lb-In (pounds inch).
What is Nm torque?
Newton metres
Torque tells you how strong an engine is. Torque is measured in Newton metres (Nm) or you might see the imperial measurement of lb-ft (pounds-feet). If you want to calculate the conversion for yourself, 1 Nm is equivalent to 0.738 lb/ft.
What is the meaning of 8.8 grade in a bolt?
In the case of a 8.8 grade bolt the first figure signifies that the Tensile Strength is at least 800MPa. The second figure signifies that the fastener will begin to yield at 80% of the Ultimate Tensile Strength, i.e. at least 640MPa.
What size bolt has a 19mm head?
Size Chart
| Bolt size | Size | Tolerance |
|---|---|---|
| 18mm | 18.40 | |
| 3/8″BSW | 18.43 | |
| M12 | 19mm | 19.46 |
| 1/2″UNF | 3/4″ | 19.51 |
What is Max torque Nm rpm?
It’s expressed in Newton-Metres (Nm), and this is what you actually feel when you’re pushed back into your seat on acceleration. A car brochure will indicate the maximum torque the engine is able to generate, and the specific RPM at which it is generated.
