ISO 898-5:20 12规定了在10°C至35°C的环境温度范围内测试时，由碳钢或合金钢制成的固定螺钉和类似螺纹紧固件的机械和物理性能。在该环境温度范围内评价符合ISO 898-5:20 12要求的紧固件（固定螺钉和类似螺纹紧固件一起考虑时使用的术语）。 根据ISO 898-5:20 12，紧固件分为指定的硬度等级，仅用于压缩应力下。 ISO 898-5:20 12适用于固定螺钉和类似紧固件: 由碳钢或合金钢制成， 具有根据ISO 68-1的三角形ISO公制螺纹， 具有粗螺距螺纹M1、6至M30和细螺距螺纹M8 × 1至M30 × 2， 具有根据ISO 261和ISO 262的直径/节距组合，以及 具有符合ISO 965-1和ISO 965-2的螺纹公差。

ISO 898-5:2012 specifies mechanical and physical properties of set screws and similar threaded fasteners made of carbon steel or alloy steel when tested at an ambient temperature range of 10 °C to 35 °C. Fasteners (the term used when set screws and similar threaded fasteners are considered all together) which conform to the requirements of ISO 898-5:2012 are evaluated at that ambient temperature range. Fasteners according to ISO 898-5:2012 are classified to specified hardness classes and are intended for use under compressive stress only. ISO 898-5:2012 is applicable to set screws and similar fasteners:

• made of carbon steel or alloy steel,
• having a triangular ISO metric screw thread according to ISO 68-1,
• with a coarse pitch thread M1,6 to M30, and fine pitch thread M8×1 to M30×2,
• with diameter/pitch combinations according to ISO 261 and ISO 262, and
• having thread tolerances according to ISO 965-1 and ISO 965-2.
