10、steners, to supersede AS/NZS 4291.1:1995, Mechanical properties of fasteners, Part 1: Bolts, screws and studs. The objective of this Standard is to provide manufacturers and users of threaded fasteners with the material requirements and mechanical properties for carbon steel and alloy steel bolts, s
11、crews and studs with ISO metric threads. The following changes have been incorporated in this edition: (a)Updating of references. (b)Addition of a permissible boron content in material composition. (c)Introduction of a torsional strength requirement for bolts and screws with property classes 8.8 to
12、12.9 with nominal thread diameters equal to or less than 4 mm and for short bolts and screws with nominal thread diameters greater than 4 mm and equal to and less than 10 mm. (d)Modification of marking requirements including the clock-face system for property class. This Standard is identical with a
