Утвержден и введен в действие Постановлением Государственного комитета СССР по стандартам от 30 апреля 1981 г. № 2262.

1. Настоящий стандарт распространяется на трапецеидальную однозаходную резьбу с профилем по ГОСТ 9484-81, диаметрами и шагами по ГОСТ 24738-81 и устанавливает номинальные диаметры резьбы.

Стандарт полностью соответствует СТ СЭВ 838-78.

2. Номинальные диаметры резьбы должны соответствовать указанным на чертеже и в таблице.

рис. 1

d — наружный диаметр наружной резьбы (винта);

d_{2} — средний диаметр наружной резьбы;

d_{3} — внутренний диаметр наружной резьбы;

D_{1} — внутренний диаметр внутренней резьбы (гайки);

D_{2} — средний диаметр внутренней резьбы;

D_{4} — наружный диаметр внутренней резьбы;

P — шаг резьбы;

a_{\text{с}} — зазор по вершине резьбы;

h_{3} — высота профиля наружной резьбы;

H_{1} — рабочая высота профиля резьбы.

Значения диаметров вычислены по формулам:

D_{1} = d - 2H_{1} = d - P ;

D_{4} = d + 2a_{\text{с}} ;

d_{2} = D_{2} = d - H_{1} = d - 0,5P ;

d_{3} = d - 2h_{3} .
