Molybdenum Fasteners

Pure Molybdenum fasteners (molybdenum nuts, molybdenum washers, molybdenum screws and molybdenum threaded rods) have excellent heat resistance, with their high melting point. It’s useful for heat resistant devices such as sputtering equipment and high temperature furnaces. Metric molybdenum fasteners and ANSI standard molybdenum fasteners are available. TZM alloy and Mo-La alloy can also be made to molybdenum alloy fasteners. 

We now have the capacity of making micro molybdenum nuts and molybdenum screws as M1.5 and M2.
 

Molybdenum Threaded Rods      Inquiry

Molybdenum threaded rods (Moly bolts) are 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 Screws           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 refractory nuts are available in both inch and metric sizing. Our regular molybdenum nut is the hex nut.

Molybdenum Washers        Inquiry

Molybdenum refractory washers are available in both inch and metric sizes. Washers help to distribute the load of a threaded fastener. We can produce custom washers.

Packaging of Molybdenum fasteners (molybdenum nuts, molybdenum washers, molybdenum screws and molybdenum threaded rods) 

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