Hastelloy C22/C276 Fasteners

Where the toughest jobs meet the most challenging conditions, Hastelloy Fasteners are designed to meet everything head-on. They are a propriety mix of nickel, molybdenum, and chromium that is extremely resistant to corrosion, rust, and extreme temperatures.

They function perfectly in environments such as chemical plants, sea environments, and offshore drilling, where fasteners would otherwise fail. Hastelloy Fasteners resist heavy chemicals, seawater, extreme heat, and pressure without breaking down. They are robust enough to resist acid, chlorine, and other extreme material abrasion.

Designed to stringent standards such as ASTM B574 and ASME SB574, every fastener is put through strenuous tests to determine its strength and reliability. They are produced in a range of sizes and adjustable to fit the requirements.

Where toughness, strength, and durability are required in a project, Hastelloy Fasteners are the obvious choice. They will hold everything firmly fastened regardless of the condition.
