Ceramic Composite Nuts

Ceramic Composite Nuts (CMCs) are advanced, internally threaded fasteners designed to mate with ceramic composite or specialty alloy bolts. Manufactured from Ceramic Matrix Composites, these nuts offer a unique combination of extreme high-temperature stability (up to 1650°C), low density (lightweight), and resistance to thermal shock. They are essential in structural joints within the hottest sections of aerospace engines (gas turbines), nuclear facilities, and high-temperature research equipment where conventional metal fasteners would suffer catastrophic creep or oxidation failure. Zeron Fasteners supplies CMC nuts to ensure structural integrity and stability in the most thermally challenging environments.
