Global Nuclear-grade Bolts, Nuts and Screws Market Strategic Research Report

Scope of the Report

The global Nuclear-grade Bolts, Nuts and Screws market size is predicted to grow from US$ 518 million in 2025 to US$ 725 million in 2032; it is expected to grow at a CAGR of 5.0% from 2026 to 2032.

In 2025, global nuclear-grade bolts, nuts and screws production reached approximately 25,244 tons, with an average global market price of around US$21,000 per ton. In 2025, the global's total production capacity of Nuclear-grade Bolts, Nuts and Screws reached 34,000 tons. The industry average gross profit margin for this product is 28%-60%.Nuclear-grade bolts, nuts and screws are high-performance threaded fasteners specifically used in nuclear safety level 1, 2, and 3 equipment in nuclear power plants. They must strictly follow national standards, are made of specific stainless steel or alloy steel, have extremely high strength, precision and reliability, to work stably for a long time under extreme working conditions of high temperature, high pressure, strong radiation and strong vibration, and their performance is directly related to the integrity and operational safety of the pressure boundary of the nuclear power plant, and is a key mechanical component to prevent the leakage of radioactive materials.

The industrial chain is characterized by technology-intensive and close collaboration. The upstream is supplied with raw materials such as special steel and non-ferrous metals. The midstream is the core manufacturing link, including independent research and development, precision cold heading forming, thread rolling, quenching and tempering heat treatment and extremely strict full-process testing. The downstream is directly connected to the nuclear power engineering design, engineering construction and equipment integration unit, and the products are finally used in the reactor pressure vessel, main pipeline, main pump and other key systems of nuclear islands and conventional island equipment.

Driven by the global energy transition and the "dual carbon" goal, nuclear power has ushered in the development of clean baseload power sources, bringing continuous demand for nuclear-grade fasteners. The market is expected to maintain solid growth. The driving force for deeper prospects comes from technological progress and industrial upgrading: in order to meet the higher requirements of the fourth-generation reactor, materials are breaking through in the direction of ultra-high temperature resistance and strong radiation resistance; the manufacturing process accelerates the integration of intelligent manufacturing and digital monitoring; The focus of industry competition is shifting from a single product supply to a full life cycle service covering design, in-service monitoring, and life assessment. At the same time, localization substitution and international cooperation will reshape the global industrial pattern.
