Hastelloy B2 U-Bolts & J-Bolts

A U-Bolt is a round rod bent into a "U" shape with threads on both ends, commonly used to secure pipework against supports. A J-Bolt is bent into a "J" shape and is often used as a tie-down or embedded into concrete. Forged from Hastelloy B2 (UNS N10665), these fasteners possess phenomenal resistance to severe reducing environments, particularly non-oxidizing acids such as hydrochloric acid (HCl) and sulfuric acid, which is critical when supporting piping that carries highly corrosive media. Zeron Fastners is a trusted manufacturer and supplier of these durable and high-performance nickel alloy bolts, ensuring secure and corrosion-free pipe and structural support in the most challenging industrial conditions.
