At Ananka Fasteners Pvt Ltd, we manufacture fasteners to the dimensional requirements of ISO 8100. Hexagon bolts with flange (metric coarse thread). Integral washer-face flange spreads the bearing load and eliminates the need for a separate washer. Dimensions align with the DIN 6921 hexagon flange-bolt family. Note: ISO 8100 is an uncommon ISO reference number for flange bolts; the common ISO flange-bolt standard is ISO 4162 – values below follow the DIN 6921-equivalent geometry published by dimension references.
