1. What is a molybdenum hex bolt?

A molybdenum hex bolt is a threaded fastener made from molybdenum or a molybdenum-based alloy. It features a six-sided head for tightening with a wrench or socket and is intended for specialized industrial applications.

2. What are molybdenum hex bolts used for?

Common applications include high-temperature furnaces, vacuum processing equipment, semiconductor manufacturing systems, thermal treatment assemblies, and laboratory equipment.

3. Can molybdenum hex bolts withstand extreme temperatures?

Molybdenum has a melting point of approximately 2,623°C. However, the maximum service temperature of a bolt depends on its mechanical load, atmosphere, oxidation exposure, and design. Molybdenum oxidizes at elevated temperatures in air, so the operating environment is important.

4. Are molybdenum hex bolts available in different sizes?

Yes. Dimensions may be sourced according to project requirements, including bolt diameter, length, head dimensions, and thread specifications, subject to manufacturing capabilities and availability.

5. Are molybdenum bolts suitable for vacuum furnace applications?

Molybdenum fasteners are used in many vacuum furnace assemblies because of their high melting point and thermal stability. Compatibility depends on the temperature, load, atmosphere, and other materials in the assembly.

6. Can REG Metals source custom molybdenum hex bolts?
