Unifit Fastener is a reliable company that produces and supplies high-quality Monel nuts that provide high performance in harsh environments. Monel nuts are designed by using the high-quality nickel-copper alloys that provide excellent resistance against seawater, chemicals and corrosive media. This has rendered them suitable for marine engineering, oil and gas, petrochemicals and power plants, as well as chemical processing industries.
Some of the common grades that we offer for Monel nuts include Monel 400 and Monel K500, which is highly mechanically strong and stable at high temperatures. These nuts have outstanding hardness and resistance to life even when subjected to high pressure and other hostile environments, which guarantees these nuts a longer service life and a decreased time of maintenance.
Unifit Fastener also provides a wide variety of products, such as hex nuts, heavy hex nuts, lock nuts, nylock nuts, square nuts, flange nuts, weld nuts, dome nuts and eye nuts, among others. Every single product comes in various sizes, dimensions and bespoke fitments to individual industrial needs. Our Monel nuts have superior performance in relation to hydrofluoric acid, seawater, and acidic and oxidising conditions, which make them highly applicable in heat exchangers, condensers, seawater equipment, pumps and nuclear uses.
Each batch is subjected to rigorous quality control, such as mechanical testing, hardness testing, PMI and chemical analysis, as a form of ensuring that the batch meets international standards. Having been specialised in precision engineering, timely delivery and customer satisfaction, Unifit Fastener has positioned itself as a reliable supplier of high-performance Monel nuts in imperative applications across the globe.
