At Ananka Fasteners Pvt Ltd, we manufacture and supply fasteners certified to DIN 10083. CORRECTION: The input label ‘Bolting Fasteners (General)’ is inaccurate. ‘DIN 10083’ refers to DIN EN 10083 – Steels for quenching and tempering. It is a base bar/billet steel standard (not a fastener product standard) that defines the quenched-and-tempered carbon and alloy steels commonly used as raw material for high-strength bolting (e.g. 42CrMo4 for A193 B7-type studs). Part 1 general, Part 2 non-alloy (carbon) steels, Part 3 alloy steels.
