Functional Materials
Molybdenum Fasteners
Pure Molybdenum fasteners (nuts, washers, screw, bolts and threaded rods) have excellent heat resistance. With their high melting point, molybdenum fastener is useful for heat resistant devices such as sputtering equipment and high temperature furnaces. Metric molybdenum fasteners and ANSI standard molybdenum fasteners are all available. TZM alloy and Mo-La alloy can also be made to fasteners.
We now have the capacity of making micro molybdenum nuts and screw as M1.5 and M2.
Molybdenum Threaded Rods Inquiry
Molybdenum threaded rod (bolt) is produced for high temperature vacuum environments. They can be cut and finished off to desired lengths. In many cases, cut pieces can be coupled with washers and nuts to emulate a screw.

Molybdenum Screw Inquiry
Molybdenum screws 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 custom lengths and custom features. Please take note of the sketch provided for screw specs.

Molybdenum Nuts Inquiry
Molybdenum nuts are available in both inch and metric sizing. Our regular molybdenum nut is the hex nut.

Molybdenum Washer Inquiry
Molybdenum washer is available in both inch and metric sizes. Washers help to distribute the load of a threaded fastener. We can produce custom molybdenum washer.

Packaging of Molybdenum fasteners
Our molybdenum fasteners are wrapped in foam and packaged in crate or carton to ensure safe storage and transportation.
