At Ananka Fasteners Pvt Ltd, we manufacture fasteners to the dimensional requirements of ISO 8102. Hexagon head bolts with flange (plain or serrated/toothed flange), metric coarse thread. The flanged head distributes clamp load; the serrated variant resists loosening. Geometry aligns with the DIN 6921 flange-bolt family. Published dimension references list ISO 8100 and ISO 8102 with the same DIN 6921-equivalent size table.
