Russ Fasteners is a trusted producer and supplier of Hastelloy Bolts in Pulau Ujong, Singapore, offering industrial-grade fastening solutions for chemically corrosive and high-temperature conditions. The bolts are produced from corrosion-resistant Hastelloy alloys such as C-22 and C-276, which have the ability to maintain strength and durability in harsh chemical exposure. Russ Fasteners guarantees every bolt to be precision-machined and performance-tested for use in extremely demanding industrial applications. Hastelloy Bolts, which are ideal for reactors, pressure vessels, and marine installations, have long service life and are also resistant to both reducing and oxidizing conditions.
Hastelloy Bolts consist of nickel (more than 50%) and chromium (up to 22%), molybdenum (up to 16%), and iron, with the formation of alloys like Hastelloy C-276 or C-22. These bolts have tensile strength ranging from 690–800 MPa and are resistant to chemical corrosion, particularly in sulfuric, hydrochloric, and nitric acid environments. They are pitting-resistant, stress corrosion cracking-resistant, and oxidation–resistant at high temperatures. The Hastelloy Bolts are also resistant to mechanical performance at temperatures above 1000°C and are best used in chemically and thermally aggressive applications.

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 Bolts are used in chemical processing plants, offshore oil platforms, nuclear reactors, and marine environments. They provide clamping of pipe flanges, heat exchangers, pumps, and tanks with exposure to aggressive acids, chlorides, and oxidizing agents. Inside high pressure equipment and heat in the power generation and pollution control equipment, they are used. In equipment having provisions for gas scrubbers, pharmaceutical machinery, and equipment handling food, material integrity is the prime requirement. Hastelloy Bolts are critical for use in maximum corrosion resistance, durability over a long period, and mechanical properties in harsh service conditions.
To further protect our Hastelloy bolts, Russ Fasteners takes extra care while packing them. Every bolt is covered with protective materials to ensure that it is not damaged, corroded or contaminated in any way during transportation. Our packaging products include strong cartons and special packaging that meets your requirements. We ensure that all our products are well packed and labeled in a manner that makes it easy to identify and handle the products to ensure that we deliver quality products in good condition.
