Fajar Metals stands out as a top manufacturer and supplier of Monel Nuts, proudly based in Jakarta, Indonesia. We specialize in providing robust fastening solutions tailored for critical applications across marine, chemical, aerospace, and oil & gas industries. Our nuts, crafted from high-performance Monel alloys like Monel 400 and Monel K500, are designed to offer exceptional corrosion resistance, especially in challenging environments such as seawater, acidic, and alkaline conditions. Adhering to international standards like ASTM F467 and ASME B18.2.2, we offer a diverse range of sizes, thread types, and coatings. At Fajar Metals, we guarantee high mechanical integrity, precise dimensional accuracy, and lasting reliability in every fastener we produce.
Monel Nuts are primarily crafted from Monel 400, which contains about 63% nickel and 30–33% copper, or Monel K500, which incorporates aluminum and titanium for enhanced strength. These nuts are known for their outstanding resistance to seawater, hydrofluoric acid, alkalis, and chloride stress corrosion. Monel 400 boasts tensile strengths ranging from 480 to 620 MPa, while Monel K500 can surpass 900 MPa. Our nuts come in both cold-worked and age-hardened conditions, manufactured with meticulous threading and tolerance control. At Fajar Metals, we ensure that each nut consistently performs well under high stress, thermal cycling, and corrosive exposure in demanding industrial settings.
