Tricon Steel & Alloys is a leading monel fasteners manufacturer, supplier, and exporter; we proudly present monel fasteners. Monel Fasteners are a nickel-copper alloy known for their exceptional corrosion resistance, high strength, and excellent durability.
Monel fasteners are primarily composed of copper (28–34%) and nickel (minimum 63%), with possible trace amounts of additional elements such as iron (up to 2.5%), manganese (up to 2%), and minor levels of silicon, sulfur, and carbon. This alloy, monel alloy 400, exhibits remarkable corrosion resistance, excellent weldability, and moderate to high strength. It is highly suitable for various applications in the oil, gas, maritime, and chemical processing industries.
Monel Screws, Monel Bolts, and Monel Nuts have remarkable qualities, including strong corrosion resistance and great strength. Made of the anti-corrosion alloy Monel, these fasteners guarantee endurance and durability in challenging conditions. Monel fasteners are perfect for many uses where resistance to corrosive elements is essential, such as in chemical processing and marine engineering. Our fasteners are a well-known and durable option that offers resistance, efficiency, and structural integrity in various industrial environments. We provide precision engineering for reliable fluid conveyance solutions.
The company is committed to delivering top-quality Monel fasteners that meet international standards and exceed customer expectations. With our expertise and advanced manufacturing techniques, we ensure reliable performance and long-lasting service life for our valued customers.
We put quality first, putting all of our materials through extensive testing before delivery. The Hardness Test, Chemical Analysis, PMI Testing, Micro and Macro Test, Flaring Test, Pitting Resistance Test, and Flattening Test are some of these tests. Invoices, packing lists, and a legalised Certificate of Origin are among the documents we offer. To ensure total client satisfaction, we also provide a certificate of third-party inspection.

Cold Forging
This initial process is a cold forging process used to produce a near net shape work billet. An important consideration in cold forging is the tendency for the bar tobolts Manufacturing Process buckle if its unsupported length to diameter ratio is too high. This ratio usually is limited to less than 4:1 but with suitable dies, therefore, cold forging is the most likely production method because bolts have a large head-to-shank ratio, they are longer than 1½ times their diameter, bolts have multiple diameters and finally require a geometrical shap
Thread rolling
The next process applied to the bottom of the work billet is a bulk deformation process known as "thread rolling". This type of cold-forging process is used bolts Manufacturing Processbecause cylindrical can easily have thread applied by rolling the work billet through two dies. The thread rolling process is usually chosen over machining because thread rolling provides higher production rates, more effective material usage, stronger thread due to work hardening and finally better fatigue resistance because the work billet undergoes compressive stresses during the rolling process.
Blackening and Galvanization
The final process induced on the now almost complete bolt is the application of an anti-corrosive layer, to stop oxidation. The usual process is called "blackening"; Either process chemically or physically coats the surface of ferrous metals, creating a strong barrier against humidity and corrosion. Hot Blackening is most popular & common blackening processes:
Hot Blackening
Hot blackening involves dipping the bolt into six different tanks. The bolt is usually "dipped" by automated part carriers for transportation between tanks. These tanks contain, in order, alkaline cleaner, water, caustic soda at 450°C to 500°C and finally the sealant, which is usually crude oil. The caustic soda bonds chemically to the surface of the metal, creating a porous base layer on the bolt.

Types of Duplex Fasteners
Duplex fasteners come in various types, each designed to serve specific purposes in different applications. The most common types of duplex fasteners include:
Duplex Bolts: These are threaded fasteners with a head and a shank, designed to be used with nuts for fastening two or more components together. Duplex bolts are available in different lengths, diameters, and grades to suit specific requirements.
Duplex Nuts: Nuts are used in conjunction with bolts to create a threaded fastening system. Duplex nuts are designed to provide secure and corrosion-resistant connections in challenging environments.
Duplex Screws: Similar to bolts but typically shorter, screws are threaded fasteners that can be used for a variety of applications. Duplex screws are corrosion-resistant and can be employed in situations where high strength and durability are essential.
Duplex Washers: Washers are flat, thin plates with a hole in the center. They are placed between a nut and a bolt or a screw and the surface it is fastened to. Duplex washers help distribute the load evenly and provide additional protection against corrosion.
Duplex Studs: Studs are fasteners without heads that have threads on both ends. They are often used in situations where a bolt and nut combination may be impractical. Duplex studs provide a robust and corrosion-resistant solution.
Duplex Anchor Bolts: These specialized bolts are designed for anchoring structures to concrete. Duplex anchor bolts provide both high strength and corrosion resistance, making them suitable for applications where stability is crucial.
Duplex Threaded Rods: Threaded rods are long, straight rods with threads along their entire length. They are often used to create custom fastening solutions and are available in various lengths and diameters.
The choice of the specific type of duplex fastener depends on the application requirements, environmental conditions, and the level of corrosion resistance and strength needed. Manufacturers produce duplex fasteners following international standards to ensure their quality and performance in demanding industries such as oil and gas, chemical processing, and maritime applications.
