标准范围

适用于符合ISO 898-1的8.8至12.9级性能等级的螺栓和螺钉，螺纹小于M3，ISO 898-1中没有规定断裂和验证载荷，以及标称直径为3 mm至10 mm的短螺栓和螺钉，不能进行拉伸试验。最小断裂扭矩对内六角固定螺钉无效。

Applies to bolts and screws of property classes 8.8 to 12.9 in accordance with ISO 898-1 with thread less than M3 for which no breaking and proof loads are indicated in ISO 898-1, as well as to short bolts and screws with nominal diameters 3 mm to 10 mm which cannot be subjected to a tensile test. The minimum breaking torques are not valid for hexagon socket set screws.
