Monel 400 Hex Bolts

Monel 400 Hex Bolts Manufacturers & Suppliers in India

Unifit Fasteners provides high-performance Monel 400 hex bolts which are designed to be used in areas where the strength and resistance to corrosion cannot be compromised. These bolts are made of high-quality monel 400, an alloy of nickel and copper, which is much more durable in high-stress industrial service. They can survive in acidic, alkaline and salt-laden environments and hence are a reliable option in the most vital areas.

Our Monel 400 Hex Bolts have been made to last longer, having a stable nature in a broad temperature range, which remains between the sub-zero environment and the high temperatures. This renders them applicable in marine engineering, chemical processing, heat exchangers, oil and gas systems and equipment which are exposed to hydrofluoric acid. Every bolt undergoes fabrication to provide outstanding tensile and wear resistance and chloride-induced cracking of stress.

At Unifit Fasteners, all bolts are manufactured using precise machining so as to have the right dimensions, good finishing, and easy fit. To suit the project requirements, we provide tailored sizes and specifications to serve as a secure and dependable fastening solution to the most extreme applications. Our Monel 400 Hex Bolts offer a reliable and stable workload performance with a consistent quality and a focus on customer needs, which makes them a reliable option in the industry that requires uncompromised quality of performance.
