Brian Fasteners is a premium maker and distributor of Hastelloy Fasteners in Houston, USA, providing corrosion-free solutions for harsh industrial applications. Our fasteners—in the form of bolts, nuts, screws, washers, and threaded rods—are manufactured from top-grade Hastelloy grades such as C276 and C22. Engineered for unparalleled acid, chloride, and high-temperature oxidation resistance, these fasteners are employed in the world‘s most severe environments. Every fastener from Brian Fasteners is engineered to meet ASTM, ASME, and DIN specifications, providing resilient and accurate components found trustworthy in chemical, marine, and power generation applications.
Hastelloy Fasteners consist of high-performance alloys containing more than 57% nickel as the base, with added molybdenum, chromium, and iron. C276 and C22 grades provide superior corrosion resistance in reducing and oxidizing atmospheres. The tensile strength of these fasteners ranges around 100–115 ksi, yield strength around 45 ksi, and Rockwell hardness up to C30. They retain structural integrity over broad ranges of temperature and are resistant to localized attack in the form of pitting and crevice corrosion. Hastelloy fasteners excel in corrosive environments that reduce ordinary stainless steel at once.

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 Fasteners find applications in chemical processing, pulp and paper, marine engineering, and desalination plants where they are resistant to acids, chlorine, and seawater. In drug manufacturing, they provide hygienic and corrosion-free assemblies. They‘re also used in power plants and nuclear reactors, protecting equipment exposed to high heat and radiation. They’re applied in scrubbers, chlorine gas systems, and incinerators because of their oxidation and stress corrosion resistance. Hastelloy fasteners can’t do without in high-temperature furnaces, aerospace parts, and biofuel production, where chemical exposure and intense heat require the strongest fastening solutions.
