标准摘要
[中文适用范围]： 本国际标准规定了具有 MJ 螺纹、通过使上部变形为椭圆形以实现自锁功能的浮动、自对中、双耳锚螺母的尺寸，适用于以下分类：900 MPa/235 °C；900 MPa/315 °C；900 MPa/425 °C。注 1：分类中的第一个元素（900 MPa）对应于螺母在环境温度下能够承受的最小拉伸应力，而不会在测试中使用更高强度等级的螺栓时发生断裂或开裂。注 2：分类中的第二个元素是螺母能够承受的最高温度，在环境温度恢复后不会发生永久性改变。最高温度受材料或表面处理条件的限制。本国际标准仅适用于航空航天产品标准的编制。 [外文原描述]： ISO 12273:2010 specifies the dimensions of floating, self-aligning, two lug anchor nuts, with MJ threads and a self-locking feature achieved by forming the upper portion out-of-round, of the following classifications: 900 MPa/235 °C; 900 MPa/315 °C; 900 MPa/425 °C. ISO 12273:2010 is only applicable for the compilation of aerospace product standards.
