At Ananka Fasteners Pvt Ltd, we manufacture fasteners to the dimensional requirements of DIN 935. DIN 935 specifies hexagon slotted and castle nuts with metric coarse (and fine) thread, product grades A and B. Slots in the crown accept a split (cotter) pin through a cross-drilled bolt for positive locking. Corresponds to ISO 7035/7036.
