How to Calculate Weight for Nuts and Bolts

For Bolts
  1. Determine Dimensions: Measure the bolt’s diameter, length, and thread pitch.
  2. Material Density: Find the density of the bolt material (e.g., steel, brass, etc.).
  3. Volume Calculation: Use the formula:
    Volume = π × (Radius²) × Length
    (For threads, consider a reduced area calculation if precision is needed.)
  4. Weight: Multiply the volume by the material’s density.

Example:

  • Bolt Dimensions:
    Diameter = 10 mm (Radius = 5 mm), Length = 50 mm
  • Material Density: Steel = 7.85 g/cm³

 

  1. Calculate Volume:
    Volume = π × (Radius²) × Length
    = 3.1416 × (0.5 cm)² × 5 cm
    = 3.1416 × 0.25 × 5 = 3.93 cm³
  2. Calculate Weight:
    Weight = Volume × Density
    = 3.93 × 7.85 = 30.85 g

 

For Nuts
  1. Measure Dimensions: Determine the outer diameter, inner diameter, and thickness.
  2. Material Density: Identify the material’s density.
  3. Volume Calculation: Subtract the inner cylindrical area from the outer area using:
    Volume = π × (Outer Radius² – Inner Radius²) × Thickness
  4. Weight: Multiply the volume by the material’s density.

Example:

  • Nut Dimensions:
    Outer Diameter = 20 mm (Radius = 10 mm),
    Inner Diameter = 10 mm (Radius = 5 mm), Thickness = 10 mm
  • Material Density: Steel = 7.85 g/cm³

 

  1. Calculate Volume:
    Volume = π × (Outer Radius² – Inner Radius²) × Thickness
    = 3.1416 × [(1 cm)² – (0.5 cm)²] × 1 cm
    = 3.1416 × (1 – 0.25) × 1
    = 3.1416 × 0.75 = 2.36 cm³
  2. Calculate Weight:
    Weight = Volume × Density
    = 2.36 × 7.85 = 18.53 g
