ISO 3506-3:20 09规定了由奥氏体不锈钢制成的固定螺钉和类似紧固件在10°C至35°C的环境温度范围内测试时的机械性能。在较高或较低的温度下，性能会有所不同。 ISO 3506-3:20 09适用于固定螺钉和类似紧固件: -公称螺纹直径1.6 mm≤d≤24mm； -直径和螺距符合ISO 68-1、ISO 261和ISO 262的三角形ISO公制螺纹； -任何形状。 它不适用于具有特殊性能的螺钉，如可焊性。

ISO 3506-3:2009 specifies the mechanical properties of set screws and similar fasteners not under tensile stress made of austenitic stainless steel, when tested over an ambient temperature range of 10 °C to 35 °C. Properties vary at higher or lower temperatures. ISO 3506-3:2009 applies to set screws and similar fasteners: - with nominal thread diameter 1,6 mm ≤ d ≤ 24 mm; - of triangular ISO metric threads with diameters and pitches in accordance with ISO 68-1, ISO 261 and ISO 262; - of any shape. It does not apply to screws with special properties, such as weldability.
