2、 comma has been used throughout as the decimal marker.为了与国际标准组织（ISO）的现行标准条例相符，使用逗号作十进制标记。Dimensions in mm尺寸单位毫米1 Scope and field of application1 适用范围和领域This standard specifies tolerances for product grade F screws, bolts and nuts with thread diameters from 1 to 3 mm.本标准详细说明了产品等级 F 的螺纹直径为 1-3 毫米的螺丝、螺

3、钉和螺母的公差。 It is recommended that this standard should also be used for non-standardized fasteners. 本标准同样适用于非标准化的紧固件。Product grade F generally refers to the quality of products for which stringent requirements are made with respect to tolerances (e.g. in precision mechanics).产品等级F 泛指根据产品质量所制定的严格公差要求（如
