本技术报告提供了有关ISO 898-2中规定的螺母设计标准的信息，以便在静态拉伸过载下防止剥离断裂模式。 设计标准也适用于非标准化螺母或具有ISO公制螺纹（符合ISO 68-1）的内螺纹元件与螺栓配合。然而，尺寸因素，如平面宽度或与螺母刚度相关的其他特征，以及螺纹公差，可能会影响单个螺栓和螺母组件的承载能力。因此，拟进行验证试验。 注:术语“螺栓”和“螺母”用作外螺纹和内螺纹紧固件的通用术语， 分别地

This Technical Report gives information concerning the design criteria for nuts specified in ISO 898-2 so that, under static tensile overload, the stripping fracture mode is prevented. The design criteria are also applicable to non-standardized nuts or internally threaded elements with ISO metric screw threads (in accordance with ISO 68-1) mating with bolts. However, dimensional factors such as the width across flats or other features related to rigidity of nuts, and thread tolerances can affect the load ability of the individual bolt and nut assemblies. Therefore, it is intended that verification tests be carried out. NOTE The terms "bolt" and "nut" are used as the general terms for externally and internally threaded fasteners, respectively.
