At Ananka Fasteners Pvt Ltd, we manufacture fasteners to the dimensional requirements of ISO 7719. Prevailing torque type all-metal hexagon regular nuts (style 1), metric coarse thread, property classes 5, 8 and 10. Locking is achieved by a distorted/pinched all-metal thread section (no insert). Width across flats matches ISO 4032; overall height is slightly greater than a plain nut to accommodate the locking feature.
