M8 × 40 mm Molybdenum Slotted Head Screw
High-Purity Molybdenum Screw for Vacuum and High-Temperature Applications
The M8 × 40 mm Molybdenum Slotted Head Screw is a precision-machined molybdenum fastener designed for demanding high-temperature and vacuum applications.
Made from molybdenum material, this screw is suitable for applications where conventional metal fasteners may not provide the required performance at elevated temperatures.
The slotted head design allows installation with a standard flat-blade screwdriver and provides a simple and practical fastening solution for industrial equipment.
We can manufacture molybdenum screws according to customer requirements, including diameter, length, thread length, head dimensions and slot design.
