Premium Monel Bolts are made by TSM Technology using advanced manufacturing techniques and strict quality control. Our fasteners function well over time in demanding applications and satisfy international standards. Our product guarantees long-lasting, secure connections, whether you are working in offshore installations, chemical processing, or marine building.
Specialized fasteners composed of nickel-copper alloys are called products. They are in charge of steel's remarkable strength and corrosion resistance. These bolts can withstand saltwater, acids, and alkaline solutions. Because of their special composition, they are ideal for harsh settings where conventional fasteners corrode easily.

Our strict quality control system includes multiple testing methods:

For optimum performance, TSM Technology uses sophisticated production procedures. We have more than 100 precise machinery in our 50,000 state-of-the-art plant. To guarantee alloy quality, we employ controlled environment melting. Accurate dimensions are produced by the cold heading and thread rolling procedures. For particular uses, heat treatment maximizes mechanical qualities.
Raw Material Selection: We source high-purity nickel and copper from qualified suppliers.
Melting and Casting: Vacuum induction melting creates a homogeneous alloy composition.
Hot Working: Rolling and forging create the right mechanical qualities and grain structure.
Cold Forming: Bolt heads and shanks are precisely shaped by precision heading machines.
Thread Rolling: Cold rolling produces threads that are smooth, robust, and have excellent fatigue resistance.
Heat Treatment: Strength and resistance to corrosion are maximized by carefully regulated heating and cooling.
Finishing: Surface treatments offer further protection and the desired look.
Quality testing: Thorough examination guarantees material qualities and dimensional precision.
Our 50,000 square meter production plant is state-of-the-art. Eight dedicated production lines for Monel Bolts operate with advanced automation. Precision machining centers ensure tight tolerances.
