Russ Fasteners produces and distributes precision-made Hastelloy Nuts in Singapore, Pulau Ujong, for corrosion-resistant fastening items in harsh industrial environments. The nuts are made from high-end nickel-based alloys like Hastelloy C-22 and C-276 that resist highly corrosive and oxidizing conditions. Russ Fasteners guarantees each nut to conform to international standards, ensuring uniform threading, dimensional tolerances, and mechanical performance. Suitable for chemical, marine, and high-temperature uses, Hastelloy Nuts are trusted in equipment and systems where other materials deteriorate rapidly under extreme environmental stress.
Hastelloy Nuts consist of corrosion-resistant nickel, molybdenum, chromium, and iron alloys. C-22 and C-276 alloys have tensile strengths of 690–785 MPa and enhanced ductility and toughness at high temperatures. These nuts have a high resistance to uniform corrosion, pitting, and stress corrosion cracking in reducing and oxidizing agents. Their high chemical stability and mechanical strength enable them to be used in harsh environments, such as high-pressure steam, strong acids, and chlorinated solvents. Hastelloy Nuts are also non-magnetic and resistant to heat.

To satisfy our clients needs by providing high quality products at competitive price as per the schedule and to maintain long term relationship with our clients.
Hastelloy Nuts are utilized in chemical processing equipment, desalination plants, marine applications, power generation equipment, and pollution control equipment. They play a key role in bolting flanges, bolts, and threaded assemblies of reactors, condensers, heat exchangers, and scrubbers. Hastelloy Nuts guard against contamination and withstand aggressive cleaning chemicals in pharmaceutical and food processing facilities. They are critical in equipment that is exposed to hydrochloric acid, sulfuric acid, and other corrosive chemicals. Their high mechanical and corrosion resistances make them critical for fastening systems where safety, reliability, and longevity are of utmost importance.
To ensure that the Hastelloy nuts reach the customers in the best condition, Russ Fasteners takes every measure to provide a secure packing. Every nut is packed in protective materials to avoid any harm, rusting, or contamination as it moves from one place to another.
