4.88 Grade 10 External Hexagonal Nut Galvanized
Outer hexagonal nut, also known as hexagonal nut, is a commonly used connecting component in mechanical parts. They are usually used together with screws and bolts to connect two or more components. According to different standard specifications, external hexagonal nuts are divided into multiple models such as M1-M64. Meanwhile, there are different materials available, including stainless steel, carbon steel, etc. A nut is a component that tightly connects mechanical equipment, and can only be connected together with nuts and bolts of the same specification through the inner thread. For example, M4-P0.7 nuts can only be connected to M4-P0.7 series bolts (in nuts, M4 refers to the inner diameter of the nut being approximately 4mm, 0.7 refers to the distance between two threaded teeth being 0.7mm); The same applies to American products, for example, a 1/4-20 nut can only be paired with a 1/4-20 screw (1/4 refers to a nut with an inner diameter of approximately 0.25 inches, and 20 refers to 20 teeth per inch).
Zinc plating is a metal surface treatment process that forms a zinc iron alloy layer or pure zinc layer by depositing a layer of zinc on the metal surface, effectively preventing the metal from being corroded by the external environment and extending its service life. Zinc has relatively inert chemical properties and can form a dense zinc oxide film on the surface, effectively isolating the contact between air and metal. In addition, the galvanized layer can enhance the wear resistance and hardness of the metal, especially when it is scratched or worn, the zinc layer can automatically repair, ensuring the service life of the metal. Galvanized products are widely used in fields such as construction, transportation, and home furnishings due to their corrosion resistance and durability.
Common materials for outer hexagonal nuts include carbon steel, stainless steel, etc. Among them, carbon steel outer hexagonal nuts have higher strength and relatively lower prices, and are widely used in machinery and some heavy-duty equipment. Stainless steel hex nuts have high corrosion resistance and aesthetics, making them suitable for equipment that frequently comes into contact with water and humid environments, such as ships and kitchen equipment.
External hexagonal nuts are one of the indispensable components in mechanical connections. Their unique hexagonal shape, shear strength, and stable and reliable connection effect provide convenience for the installation and use of mechanical parts.
The nut specification table is a specific and detailed way to unify various types of nuts and subdivide some specifications of nuts using a table. There are many types of nuts, as well as nuts of different materials. Each type of nut has different specifications, and each type of screw also has its own mechanical properties and functions. Nuts are mainly classified according to national standards (GB), German standards (DIN), international standards (ISO), Japanese standards (JIS), American standards (ASTM/ANSI), and other standards based on their properties. Among them, national standards, German standards, and Japanese standards are represented by M (such as M8, M16), while American and English standards are represented by fractions or # to indicate specifications (such as 8 #, 10 #, 1/4, 3/8).
