압력 조임 이음쇠용 관나사－치수, 허용 오차 및 호칭 非紧压连接管螺纹第1部分:尺寸、公差和命名

发布日期： 2007-10-31

                该规格对包括螺钉号称1/16~6在内的固定用惯用螺钉的螺钉形状、尺寸、允许误差及号称的要求进行了规定。螺钉和螺母都是平行螺钉，是接头、旋塞、阀门的组成部分，用于机械组件。这些螺钉不适合用作以螺钉状态进行机密性签订的地方的签订螺钉。如果需要用该惯用平行螺钉实现气密性，可以有效地将螺钉外侧两个拧紧面压紧或插入适当的密封材料。

이 규격은 나사 호칭 1/16∼6을 포함한 고정용 관용 나사의 나사 모양, 치수, 허용 오차 및 호칭에 대한 요구 사항에 대하여 규정한다. 수나사와 암나사 모두 평행 나사이며, 이음쇠, 콕, 밸브의 구성 부품으로 기계적 조립품에 사용된다. 이들 나사는 나사 상태로 기밀성 체결을 하는 곳에 사용되는 체결 나사로는 적당하지 않다. 이 관용 평행 나사로 기밀성이 이루어져야 한다면, 나사 바깥쪽 두 조임면을 압착하거나 적절한 밀봉재를 삽입하는 것이 효과적이다.
