Monel Fasteners

Monel Fasteners contain carbon, nickel and small amounts of nickel as alloying elements. Monel fasteners are fabricated using techniques such as machining, hot-cold working and welding. Corrosion due to corroding mediums like rapidly running sea-water does not occur in Monel fasteners. This makes them effective in marine applications.


Monel has combined properties like ductility, high strength, resistance to acids and alkalis and goo thermal conductivity. Thus, Monel fasteners become ideal elements for high performance applications. The cost of Monel is high and is used only in limited applications. Fasteners are developed in varieties like J-bolt, U-bolt, L-Bolt, Screws, Hex Nuts, Nuts, and Washers. Machining on Monel Fasteners is difficult, due to their tendency to work harden quickly. Fasteners can be manufactured in two types Monel 400 and Monel K-500. Monel K-500 is added with titanium and aluminium giving it greater amount of strength. Aircraft industry makes extensive use of Monel fasteners, as they can withstand the damage cause during high speed flight friction. Monel Fasteners can also resist damage caused due to hydrofluoric acid.
