Molybdenum Screw

Molybdenum screw is a fastener made of molybdenum, a refractory metal with excellent strength, corrosion resistance, and thermal stability. Molybdenum screws are commonly used in high-temperature applications, vacuum environments, and in the semiconductor industry. They are often used as a replacement for tungsten screws, which are heavier and more prone to breakage. Molybdenum screws come in various sizes and shapes and can be customized to meet specific requirements.
