What is the minor diameter of thread?
Minor Diameter: The smallest diameter of the thread of the screw or nut. The term “minor diameter” replaces the term “core diameter” as applied to the thread of a screw and also the term “inside diameter” as applied to the thread of a nut.
How do you calculate minor diameter of a thread?
To find its minor diameter:Calculate the height of its fundamental triangle (H) using H = P × (√3) / 2. H = 2 mm × (√3) / 2 = 1.732 mm.Obtain for the minor diameter (d₁) using d₂ = d - 2 × (5 / 8) × H, d₂ = 20 mm - 2 × (5 / 8) × 1.732 mm = 17.835 mm.
