Molybdenum Threaded Rods

Molybdenum Threaded Rods are for when high strength and stability in extremely high temperatures are required.

They have an incredibly high melting point, which stands at 2620°C – as well as a high level of conductivity. They also have a moderately low point of thermal expansion.

As they have low distortion and extraordinary durability at high temperatures, they are ideal for applications that involve intense temperatures that are shielded from oxygen – as exposing the fastener to oxygen above heats of 600°C will cause it to oxidise.

Applications for a Molybdenum Threaded Rod include vacuum furnaces, glass production and space applications where oxygen is not present.

Available in a number of grades, in sizes from M5 to M12 as standard but with larger sizes available to be made to order.

If you require more information or would like to order a Threaded Rod, please contact an experienced member of our sales team by phone call or our enquiry form.

Molybdenum Threaded Rods are high-performance fastening components manufactured from high-purity molybdenum, offering exceptional strength, high melting point, and outstanding thermal stability. They perform reliably in extreme temperature environments and maintain structural integrity under heavy mechanical load. With excellent resistance to creep, oxidation (in controlled environments), and corrosion, they are widely used in high-temperature furnaces, vacuum systems, aerospace engineering, semiconductor manufacturing, and scientific equipment. These threaded rods provide secure and stable connections for critical assemblies where conventional steel fasteners fail. Their precise threading ensures easy installation, high durability, and long service life, making them ideal for demanding industrial and advanced technological applications requiring precision and reliability.
