This Standard specifies the hexagon bolts for structural bolting with large width across flats - thread specification is M12-M36, short length of thread, performance grades are 8.8 and 10.9; and the product grade is C. If other technical requirements are required, it shall be selected from current standards (such as GB/T196, GB/T197, and GB /T3098.1). The bolts specified in this Standard shall be matched with appropriate nuts (such as GB/T18230.3 or GB/T18230.4), so as to prevent connections from thread tripping due to over-twisting in high-level. 8.8s U and 10.9s U1 bolts can be used by negotiation of supplier and purchaser. The bolts must be matched with 6H hot dip galvanizing nuts, and the connections may cause thread tripping due to over-twisting.
