The molybdenum nuts are for fastening the role of parts together with bolts or screws tighten, all manufacturing machinery must be a component of a wide range of nut common GB, British standard, American standard,the subject of nuts. nuts, depending on the material is divided into several major types of carbon steel, high strength, stainless steel, steel and other product attributes corresponding to different standards of the country is divided into ordinary, non-standard (old) GB GBAmerican, British, German standard. Different sizes, thread ranges are divided into different specifications. General GB, German standard (such as the M8, M16), American, English with scores or # indicates the specifications (eg, 8 #, 10 #, 1/4, 3 M / 8)
2, the nut parts of machinery and equipment closely linking the thread through the inside of the nuts and screws of the same specifications, can be connected together, such as the M4-0.7 nut can only be used with the M4-0.7 screw with (in the nuts , M4 refers to the molybdenum nut inside diameter of about 4mm, 0.7 refers to the distance between the two thread for 0.7mm); also US-made products, such as a 1/4-20 nut only with 1/4-20 screw with (1/4 of the nut inside diameter of about 0.25 inches, 20 refers to every inch, 20 teeth).
Molybdenum nut Mo screw pairing, mainly to prevent the screw temperature leaving the nut distortion or even melting; molybdenum nut is widely used in heavy electrical equipment, high temperature equipment, and poor working environment equipment, molybdenum nut are a major characteristics, corrosion resistance, it decided to more extensive uses of molybdenum nut.
