GB/T 5785-2016 Hexagon head bolts—Fine pitch thread
Abstract
This standard specifies the type, dimensions, technical requirements, and marking of fine-threaded hexagonal head bolts. This standard applies to hexagonal head bolts with a nominal thread diameter of d=8 mm to 64 mm, fine-threaded, with performance grades of 5.6, 8.8, 10.9, A270, A470, A250, A450, CU2, CU3, and AL4, and product grades of A and B. Grade A is used for bolts with d=8 mm to 24 mm and l≤10d or l≤150 mm (according to the smaller value); Grade B is used for bolts with d>24 mm or l>10d or l>150 mm (according to the smaller value). It is recommended to prioritize the use of coarse-threaded bolts specified in GB/T 5782.
