Product Description
Molybdenum Fasteners are high-performance components made from pure molybdenum or molybdenum alloys, designed for applications requiring superior strength, corrosion resistance, and the ability to withstand extreme temperatures. These fasteners, which include bolts, screws, nuts, washers, and threaded rods, are commonly used in industries such as aerospace, electronics, energy, and chemical processing.
Molybdenum's unique properties, such as its high melting point (2623°C) and excellent thermal conductivity, make these fasteners ideal for demanding environments, including vacuum furnaces, high-temperature assemblies, and chemical reactors.
Features and Properties
High-Temperature Performance: Resistant to deformation and oxidation at temperatures up to 1900°C in inert or vacuum atmospheres.
Corrosion Resistance: Excellent resistance to chemical corrosion, particularly in aggressive environments.
Strength and Durability: High tensile strength and excellent mechanical stability under extreme conditions.
Customizable: Available in a wide range of sizes, thread types, and head designs to meet diverse application requirements.
Precision Manufacturing: Tight tolerances ensure reliable performance in critical assemblies.
Production Method and Production Equipments
Production Process:
Material Selection: High-purity molybdenum is selected as the raw material.
Rod/Billet Formation: Molybdenum is processed into rods or billets through hot or cold working techniques.
Precision Machining: Fasteners are formed using CNC machining to ensure high precision and tight tolerances.
Threading and Finishing: Threads are added, and the surface is treated to enhance durability and appearance.
Quality Inspection: Each fastener undergoes rigorous testing to ensure compliance with customer requirements.
Key Equipment:
CNC machining tools
Thread cutting machines
Vacuum annealing furnaces
Polishing and surface finishing machines
Applications and Related Industries
Aerospace: Used in high-temperature engine components and structural assemblies.
Electronics: Essential for semiconductor manufacturing and high-vacuum systems.
Energy: Supports components in nuclear and solar power systems.
Chemical Processing: Ideal for high-temperature reactors and corrosive environments.
Vacuum Technology: Common in vacuum furnaces and high-temperature chambers.
Interesting Facts
Thermal Stability: Molybdenum fasteners maintain strength even in extreme thermal cycling environments.
Versatility: They are compatible with other refractory metals like tungsten, tantalum, and niobium for hybrid applications.
Long Lifespan: Their durability in harsh conditions makes them cost-effective over time.

Details of Molybdenum Fasteners
Molybdenum Threaded Rod
Molybdenum rods with threads can handle high temperatures and evaporate heat. They can be cut down to various sizes and used with washers/nuts to make custom screws.
Molybdenum Screw
Molybdenum screws can handle high temperatures and heat evaporation. SSC sells these screws in different sizes, including fillister, pan, and flathead. They use both ANSI and metric sizes. We usually make screws that are the same length, but we can make them longer or shorter depending on what the customer wants.
Molybdenum Nut
Molybdenum refractory nuts can withstand high temperatures and thermal evaporation. They can be made in any size or shape (hex being the most common)
Molybdenum Washer
Molybdenum washers can withstand high temperatures and heat evaporation. They can be made in inch, metric, or other shapes. Their job is to spread out the weight of thread fasteners.
