Abstract

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.
