At Ananka Fasteners Pvt Ltd, we manufacture fasteners to the dimensional requirements of DIN 6331. Hexagon nuts with collar (round bearing flange) and a height of 1.5 x nominal diameter. The integral collar increases bearing area and protects the mating surface while the tall body gives high thread engagement; commonly used with fixture/jig components. Thread M8-M36, coarse pitch.
