Molybdenum And Molybdenum Alloy Bolts Nuts And Screws
1. Molybdenum and molybdenum alloy bolts, nuts, and screws are described as follows:
The molybdenum screw is a device that gradually fastens the components of the utensils using the mathematical and physical principles of circular rotation and friction of the object. Fasteners are referred to as molybdenum screws in general. Molybdenum bolts are only used in engineering construction, industrial production, engine equipment, etc., because molybdenum screws have high temperature resistance, corrosion resistance, and are not easy to deform, especially in industrial production applications. In many environments The production equipment needs to have molybdenum screws with high temperature resistance, so as to ensure that the equipment will not loosen or fall off under high temperature, which is the credit of the molybdenum bolts.
