This International Standard specifies the characteristics of hexagon head screws with thread to head and threads from M1.6 to M64, with product class A for threads from M1.6 to M24 and nominal lengths 10 d or 150 mm, whichever is the smaller, and with product class B for Threads over M24 or nominal lengths > 10 d or 150 mm, whichever is smaller, are fixed. NOTE These hexagon head screws correspond to those according to ISO 4014. They only have threads up to the head and are commercially only specified in nominal lengths of up to 200 mm. If, in special cases, specifications other than those listed in this standard are required, these can be found in the relevant ISO standards, e.g. B. ISO 724, ISO 888, ISO 898-1, ISO 965-1, ISO 3506-1, ISO 4753 and ISO 4759-1.
