Molybdenum Shoulder Bolts

Molybdenum Shoulder Bolts

Molybdenum shoulder bolts possesses a very high melting point of 2620°C, a low coefficient of thermal expansion and a high level of thermal conductivity. Because molybdenum bolts 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 fasteners to oxygen above 600°C will cause them to readily oxidize.

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

Molybdenum Shoulder Bolt Features and Benefits

Molybdenum shoulder bolts, also called stripper bolts are a unique fastener with three main parts: head, shoulder, and thread. The head has the largest diameter and is where the torque is applied, typically with a socket driver. The shoulder is smooth and unthreaded, and has a set diameter and length. The shoulder’s role is to act as a shaft or dowel for rotating parts, axles for rolling parts, guides for sliding elements, and pivot points. The final part of a molybdenum shoulder bolt is the threaded shaft. The threaded portion of a shoulder bolt has a major diameter slightly smaller than the shoulder diameter.
