At Ananka Fasteners Pvt Ltd, we manufacture fasteners to the dimensional requirements of ISO 4015. ISO 4015 specifies hexagon head bolts with a reduced shank (waisted shank, diameter approx. equal to the thread pitch diameter), product grade B, thread sizes M6-M39. The reduced shank improves fatigue/elastic behaviour under dynamic load. Head dimensions match ISO 4014.
