标准摘要
[中文适用范围]： 本文件规定了符合 ISO 261 且基本轮廓符合 ISO 68-1 的 ISO 通用公制螺纹 (M) 的螺距和牙顶直径的极限偏差。 规定的极限偏差源自本文件中规定的基本偏差和公差，适用于具有推荐公差等级的 ISO 通用公制螺纹。 [外文原描述]： This document specifies limit deviations for pitch and crest diameters for ISO general purpose metric screw threads (M) conforming to ISO 261 having basic profile in accordance with ISO 68-1. The limit deviations specified are derived from the fundamental deviations and tolerances specified in ISO 965-1. This document is applicable to ISO general purpose metric screw threads with the recommended tolerance classes.
