How M36×2.0 Dimensions Are Calculated
All dimensions on this page are calculated from ISO 724 formulas using the nominal diameter (36 mm) and pitch (2.0 mm):
- Fundamental triangle height: H = (√3/2) × P = 1.7321 mm
- Pitch diameter: d₂ = d − 0.6495 × P = 34.701 mm
- Minor diameter (external): d₁ = d − 1.2269 × P = 33.5462 mm
- Minor diameter (internal): D₁ = d − 1.0825 × P = 33.835 mm
- Thread depth: 5H/8 = 1.0825 mm
- Tensile stress area: Aₛ = (π/4) × ((d₂ + d₃)/2)² = 906.81 mm²
