Bolt Weight Calculator Metric
Bolt weight calculator metric is an essential tool for engineers, constructors, and DIY enthusiasts. It helps determine the weight of bolts based on their diameter, length, and material. This information is crucial for designing structures, calculating loads, and ensuring safety.
- Enter the diameter and length of the bolt in millimeters.
- Select the material of the bolt.
- Click ‘Calculate’.
The calculator uses the formula for the volume of a cylinder (V = πr²h) and the density of the material to calculate the weight. The formula is as follows:
Weight = π * (diameter/2)² * length * density
| Material | Density (kg/m³) |
|---|---|
| Stainless Steel | 7930 |
| Carbon Steel | 7850 |
- Always round up to the nearest whole number when calculating the number of bolts needed.
- Consider using heavier bolts in high-vibration or high-stress areas.
What if I don’t know the material of the bolt?
You can estimate the weight using the density of stainless steel, as it’s the heaviest common bolt material.
