scope:

This International Standard specifies the characteristics of hexagon head screws with threads from M1,6 up to and including M64, of product grade A for threads M1,6 to M24 and nominal lengths up to and including 10 d or 150 mm, whichever is shorter, and product grade B for threads over M24 or nominal lengths over 10 d or 150 mm, whichever is shorter.

NOTE This type of product is the same as that covered by IS04014 with the exception of threading up to head and nominal length up to and including 200 mm as popular lengths.

If, in special cases, specifications other than those listed in this Intemational Standard are required, they should be selected from existing Intemational Standards, for example IS0 724, IS0 888, IS0 898-1, IS0 965-1, IS0 3506-1 , IS0 4753 and IS0 4759-1.
