This standard specifies the characteristics of hexagon head bolts with threads from M5 to M64, full thread, of property classes 3.6, 4.6 and 4.8, and of product grade C.
Note: This type of product is the same as that covered by IGB/T 5780 with the exception of full thread.
If specifications other than those listed in this standard are required, they should be selected from existing standards (for example GB/T 196, GB/T 3106, GB/T 3098.1 and GB/T 3103.1).
