Molybdenum Screws, Fasteners and Fixings

Molybdenum is a silvery-white metal that is very ductile and incredibly resistant to corrosion.

It easily forms compounds with other elements and is recovered as a by-product from the mining of tungsten or copper.

It’s mostly found in small amounts in missiles, engines, electric heater filaments, but commercial use often finds molybdenum as part of an alloy.

When in use in fasteners, they maintain strength at elevated temperatures – as they have a very high melting point of 2620 degrees centigrade, as well as a high level of thermal conductivity and low thermal expansion rate. Because they can withstand temperatures without changing shape, expanding or softening significantly, they’re ideal for high-temperature vacuum furnaces, glass production and military applications.

Exposure to temperatures above 600 degrees will cause a molybdenum fastener to oxidise. 

We are able to provide nuts in molybdenum in sizes ranging from M1.6 to M6 as standard, with molybdenum washers also in sizes ranging from M1.6 to M6 and bolts in sizes from M1.6 x 10mm to M5 X 10mm.
