Molybdenum Button Head Cap Screws

Molybdenum Button Head Cap Screws

Molybdenum button head cap screws possess a very high melting point of 2620°C, a low coefficient of thermal expansion and a high level of thermal conductivity. Because molybdenum screws have the ability to withstand extremely high temperatures without changing shape, expanding or softening significantly, they are ideal for high strength / high temperature applications that are shielded from oxygen. Exposing molybdenum button head cap screws to oxygen above 600°C will cause them to readily oxidize.

As a result, molybdenum button head cap screws find their way into high temperature vacuum furnaces, glass production, military and space applications where oxygen is not present.

Molybdenum Button Head Cap Screw Features & Benefits

Molybdenum button head cap screws combine the similar shape of a pan head with the driver of a socket head. The socket driver is ideal for low clearance applications that require a large area clamping face. Compared to a standard socket head cap screw, molybdenum button heads have a lower and wider profile. This can be useful when the clamping material is too thin to counter-bore.

Advantages

· Wide bearing surface for clamping

· Low profile head
