Hastelloy C276 Hex Bolts

Hastelloy C276 Hex Bolts are threaded fasteners made from one of the most versatile corrosion-resistant alloys available. The material, Hastelloy C276, is a nickel-molybdenum-chromium alloy with exceptional resistance to a wide range of chemical process environments, including strong oxidizers and reducing agents, wet chlorine, and hypochlorite. These bolts are essential in industries like chemical processing, pollution control, and waste treatment, where exposure to extremely aggressive, hot, or contaminated media is routine. A Hex Bolt features a six-sided head, allowing for high torque application using a wrench. Zeron Fasteners manufactures and supplies reliable, high-integrity nickel alloy Hex Bolts to ensure the secure and long-lasting assembly of critical equipment.
