ISO 16047:2005规定了对螺纹紧固件和相关零件进行扭矩/夹紧力试验的条件。它基本上适用于碳钢和合金钢制成的螺栓、螺钉、螺柱和螺母，其机械性能在ISO 898-1、ISO 898-2或ISO 898-6中有规定，具有ISO公制螺纹，螺纹尺寸为M3至M39。根据ISO 68，它也适用于具有三角形ISO螺纹的其他外螺纹和内螺纹紧固件的组合。不适用于未承受拉伸应力的固定螺钉和类似螺纹紧固件，也不适用于形成自身配合螺纹的螺钉或具有额外自紧力的螺纹紧固件- 锁定功能。

ISO 16047:2005 specifies the conditions for carrying out torque/clamp force tests on threaded fasteners and related parts. It is applicable, basically, to bolts, screws, studs and nuts made of carbon steel and alloy steel, whose mechanical properties are specified in ISO 898-1, ISO 898-2 or ISO 898-6, having ISO metric threads with thread sizes M3 to M39. It is also applicable to the combination of other externally and internally threaded fasteners with a triangular ISO thread according to ISO 68. It is not applicable to set screws and similar threaded fasteners that are not under tensile stresses, nor to screws which form their own mating thread or threaded fasteners having additional self-locking features.
