At Ananka Fasteners Pvt Ltd, we manufacture and supply fasteners certified to EN 10069. Listed by a competitor under ‘bright steel products’. The current European standard for bright (cold-drawn, peeled, ground) steel bar for machining fasteners is EN 10277 (formerly EN 10277-1 general technical delivery conditions), which superseded earlier national bright-steel standards. Covers dimensional tolerance, surface and mechanical requirements of bright bar in non-alloy, free-cutting and heat-treatable steels.
