Метрическая резьба

82. Основные размеры метрической резьбы, мм (по ГОСТ 9150-81, ГОСТ 8724-81, ГОСТ 24705-81)

d, D - наружные диаметры соответственно наружной резьбы (болта) и внутренней резьбы (гайки);

d₂, D₂ - средние диаметры соответственно болта и гайки;

d₁, D₁ - внутренние диаметры соответственно болта и гайки;

d₃ - внутренний диаметр болта по дну впадины;

P - шаг резьбы;

H - высота исходного треугольника.

Номинальные значения диаметров резьбы должны соответствовать указанным на чертеже и в таблице.

Значения диаметров вычислены по следующим формулам:

Н = 0,866025Р.

D₂ = D – 2(3/8)H = D – 0,649519053P

d₂ = d -2(3/8) = d - 0,649519053Р;

D₁ = D – 2(5/8)H = D – 1,082531755P;

d₁ = d - 2(5/8)H = d – 1,082531755P;

d₃ = d - 2(17/24)H = d – 1,226869322P.
