Hastelloy C276 Rivets

Hastelloy C276 Rivets are permanent fasteners used to join two or more pieces of material together. Unlike threaded fasteners, rivets utilize a pre-formed head and a deformable tail (bucked end) to create a strong, tamper-proof joint. This type of connection is highly reliable under vibration and shear stress. By using the super-alloy Hastelloy C276, a premier nickel-molybdenum-chromium alloy, these rivets offer unmatched corrosion resistance against aggressive environments, including wet chlorine, hypochlorites, and complex acids. They are widely used in critical applications within the chemical processing, aerospace, and pressure vessel manufacturing sectors where long-term joint integrity is paramount. Zeron Fasteners manufactures and supplies reliable, high-strength nickel alloy Rivets in various styles to meet exacting industry specifications.
