DIN EN 14399 3 Standard High strength bolting assemblies for preloading- part 3 - system HR hexagon bolt and nut assemblies 的尺寸
技术历史及DIN EN 14399 3的国际对应物
在欧洲，有两种解决方案可实现螺栓/螺母/垫圈组件所需的延展性：HR 系统和 HV 系统。这两种系统都经过充分验证，但务必避免混淆两种系统的组件。因此，这些系统均采用标准化的单一部件，且同一系统内各组件的标记也应统一（表 1）。预紧螺栓组件对制造和润滑方面的差异非常敏感；因此，务必由同一制造商提供组件，并始终对其功能和涂层负责。包装/包装盒和/或随附的商业文件上必须加贴 CE 标志。除了单个组件的适用性外，该规范还提供了如何实现组件功能所需的正确预紧力的流程。
