Metal fasteners suitable for use in extreme conditions

Goodfellow offers a variety of refractory metal fasteners (nuts, bolts, and washers) in sizes from M3 to M6 for applications that involve high temperature, high voltage, magnetism, and harsh corrosive environments.

The four chemically inert metals currently offered — tungsten, tantalum, niobium, and molybdenum — feature melting points of more than 4,352 degrees F, high hardness at room temperature, relatively high density, and stability against creep deformation at very high temperatures.
