At Ananka Fasteners Pvt Ltd, we manufacture fasteners to the dimensional requirements of ISO 10663. Hexagon nuts with flange, style 2, metric FINE pitch thread, product grades A and B. A plain (free-spinning) hex flange nut – NOT a prevailing-torque nut. NOTE: source description (‘Prevailing Torque Flange Nut’) is incorrect; the prevailing-torque all-metal fine-pitch flange nut is ISO 12126. Corrected here. Dimensions align with ISO 4161 (coarse-pitch counterpart).
