DIN 931 Hex Bolt Hexagon head bolts with shank
China manufacturer of DIN 931 Hex Bolt Hexagon head bolts with shank
Hex Bolt,known as Hexagon head bolts ,which are intended for mounting steel components together with nuts and washers, or directly in threaded holes together with washers. The bolt has an undersize thread (6az) before hot-dip galvanization and is only compatible with nuts that have normal thread tolerance (6H).
Hex bolts can be either fully threaded or partially threaded.
