Molybdenum Fastener

Molybdenum fasteners have excellent heat resistance, with their melting point being at 2,623ºC. Useful for heat-resistant devices such as sputtering equipment and high-temperature furnaces. Available in all sizes.

T&D supplies all sizes of Tungsten and Molybdenum fasteners. The normal sizes are #10, 1/4” -20, 3/8” -16, 1/2” -13

Molybdenum Threaded Rods

Molybdenum threaded rods are produced for high-temperature vacuum environments. These refractory threaded rods 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

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, but can also produce custom lengths and custom features. Please take note of the sketch provided for screw specs.

Molybdenum Nuts

Molybdenum refractory nuts are available in both inch and metric sizing. We stock many sizes/shapes and offer a same day shipping policy. Our most popular shape is the hex.

Molybdenum Washers

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

Our trays/boats can be with or without rivets, welded, or non-welded according to the specifications provided in your technical drawings. All charge carriers are available according to the specifications detailed in your technical drawings.

We can also supply aluminum trioxide-coated trays/boats.

We strongly recommend you choose Lanthanum-Molybdenum or TZM Moly material folded design trays/boats. They can be used for a long time under 1700ºC. Please review the attached boat sketch.

We can supply the plates and trays with holes meeting your requirements. Moly and Tungsten spacers are available. Unique spacer designs are also available.

The normal thickness is 0.100”, 0.125”, 0.15”, 0.200”. all other thickness material is available. However, we can provide any width, height, and length of trays/boats.
