This part of ISO 3506 specifies the mechanical properties of bolts, screws and studs made of austenitic, martensitic and ferritic steel grades of corrosion-resistant stainless steels, when tested over an ambient temperature range of 10 °C to 35 °C. Properties vary at higher or lower temperatures.This part of ISO 3506 applies to bolts, screws and studs. with nominal thread diameter d u 39 mm,. of triangular ISO metric threads with diameters and pitches in accordance with ISO 68-1, ISO 261 and ISO 262, and. of any shape.It does not apply to screws with special properties, such as weldability.NOTE The designation system of this part of ISO 3506 can be used for
