Product Description
iso grade 12.9 threaded rod and bar
ISO grade 12.9 is one kind of alloy quenched and tempered grade in ISO898 standard.ISO grade 12.9 threaded rod is usually metric threaded rods.
ISO grade 12.9 Threaded Rod we produce is manufactured with rolled threads instead of cut, free from tears or tool marks typically found in cut threads. So the threaded rods are smoother and have less surface imperfections that may cause possible failure in severe service applications.
ISO grade 12.9 threaded rod is famous for its high demand because of its high strength, excellent heat resistance and resistance to corrosion.
