High Purity Molybdenum Rods Molybdenum Screws / Fasteners M2 M3 M5 M6 Furnace Parts
Molybdenum screws / bolts are produced for high temperature vacuum environments. We produce three head types (fillister, pan & flat) in both ANSI and metric sizes. We stock these refractory screws in standard lengths, but can also produce customized lengths and features.
Pure molybdenum is useful in many high temperature applications where high melting points are required. Molybdenum also exhibits good strength at elevated temperatures making moly useful in furnace, aerospace, and similar applications. And Molybdenum's good thermal and electrical conductivity and low coefficient of expansion make it a useful metal in electronic/electrical and glass-to-metal sealing applications.
