The finishes available are ENP, Zinc Plating, Zylan Coating, HDG, Zinc Flake and Zinc Phosphatizing. Electro Polishing option for stainless steel fasteners is also available. Thread rolling of studs is done after heat treatment process to avoid dent/damage.

This also helps improve mechanical properties, prevent decarburization and gives better gauge fitment as heat treatment surface distortion is removed by centre-less grinding process, which is carried out just before thread rolling. Our studs are both side chamfered and are available in rolled thread diameter starting M6 (1/4”) to M110 (4 1/2”) for any length.
