Sumit Impex is a reliable manufacturer, supplier and exporter of Monel K500 Fasteners. We offer a wide range of Monel K 500 Nuts, Monel K 500 Bolts, Monel K-500 Stud Bolts, Monel K-500 Washers and Monel K500 Round Bars. We manufacture our fasteners from high quality Monel K500 alloy (UNS N05500 / WERKSTOFF 2.4375) which is a nickel copper alloy known for its high strength, long-lasting durability, and resistance to corrosion. Our fasteners find common applications in the marine, offshore, chemical and power generation industries, where it needs to perform well even in demanding industries.
Our Monel K500 alloy has the same superior resistance to corrosion as Monel 400, but it is harder and stronger as it has been aged with aluminum and titanium. Because of this, our Monel K500 fasteners and bolts are very resistant to seawater, non-oxidizing acids, alkalis, and sour gas environments, even when the temperature is high. It maintains its excellent mechanical properties over different temperatures and is much better at resisting stress-corrosion cracking, cavitation, and fatigue. Because of these advanced features, Monel K500 fasteners are ideal for pumps, valves, shafts, turbines, and marine hardware that will be used in saltwater or chemical processing environments.

Our Monel Din 2.4375 fasteners, nuts, bolts, washers, and stud bolts are used in industries like offshore oil rigs, marine engineering, desalination plants, chemical processing, petrochemical refineries and power generation facilities. Our fasteners perform well in places where both high strength and resistance to rust are needed. The Monel K500 round bar we use in our fasteners makes it even more durable making it ideal for use in high-load and high-temperature situations.
As a quality-oriented manufacturer, we ensure that each product meets stringent quality and international specifications. We provide detailed documentation, including Mill Test Certificates (MTCs), Raw Material Test Reports, Heat Treatment Charts, Certificates of Origin, and Quality Assurance Plans (QAPs). We test each fastener very carefully to make sure it is the right size, strong enough and resistant to rust. We use strong packaging methods like wooden crates, pallets, shrink wraps, and carton boxes to ensure that nothing gets damaged during shipping.
