Hexagonal stainless steel nut nut
Definition and structure
Definition: Hexagonal stainless steel nuts and nuts are a common fastener. Nut is a part with internal threads, usually used in conjunction with bolts or screws, to fasten two or more parts together through the screwing of threads; nut is a common name, but it is actually the same concept as nut.
Structure: The hexagonal shape is its most striking feature. It has six equidistant sides, a shape that makes it easier to operate when tightening or loosening with a tool (such as a wrench) and provides better torque transfer. There are precise threads inside, and the specifications of the thread (such as pitch, tooth profile, etc.) determine what kind of screw it matches. Threads are usually divided into coarse threads and fine threads. Coarse threads have a larger pitch and relatively higher strength under the same nominal diameter. Fine threads are more suitable for occasions that require precise adjustment or are sensitive to vibration.
Material properties
Advantages of stainless steel: Made of stainless steel, it has good corrosion resistance. This allows the hexagonal stainless steel nut and nut to maintain good performance in environments with humid and corrosive media (such as seawater, chemical gases, etc.). For example, in the assembly of marine engineering equipment and chemical equipment, ordinary carbon steel nuts are prone to rust and corrosion, while hexagonal stainless steel nuts and nuts can perform a long-term and stable fastening function.
Material strength: Stainless steel materials come in different strength levels. Generally speaking, they are strong enough to withstand a certain amount of tension and pressure to ensure the firmness of the connection. Its strength can be roughly distinguished by the material number. For example, the common 304 stainless steel nuts and nuts have better comprehensive properties, including strength and corrosion resistance; while the 316 stainless steel nuts and nuts have excellent performance in corrosion resistance, especially seawater corrosion resistance. Better, the strength can also meet the needs of most industrial applications.
Specifications and Standards
Specification expression method: The specifications of hexagonal stainless steel nuts and nuts are mainly expressed by nominal diameter, pitch and thickness. The nominal diameter refers to the outer diameter of the screw that matches it. For example, the nominal diameter of an M8 nut is 8mm. This size determines that it can be screwed with the M8 screw. Pitch is the axial distance between adjacent thread teeth, and different pitches are used in different application scenarios. Thickness affects the load-bearing capacity and tightening effect of the nut. Thicker nuts can usually withstand greater pulling force.
Standard system: They follow a variety of standards, such as International Standards (ISO), Chinese National Standards (GB), American Society of Mechanical Engineers Standards (ASME), etc. These standards specify the dimensions, tolerances, material properties and many other details of nuts and nuts. For example, hexagonal nuts produced in accordance with GB/T 6170-2015 standards have strict regulations in terms of dimensional accuracy, thread quality, etc. to ensure product versatility and interchangeability.
Machinery manufacturing: widely used in the assembly of various mechanical equipment. For example, in the assembly of automobile engines, hexagonal stainless steel nuts and nuts are used to fasten cylinder heads, crankcases and other components to ensure that the various components of the engine are firmly connected in high-temperature and high-speed operation environments. In machine tool manufacturing, it is used to fix components such as the bed and worktable to ensure the accuracy and stability of the machine tool.
Construction Industry: Plays an important role in the connection of building structures. For example, in steel structure buildings, it is used to connect steel beams, steel columns and other components. Its corrosion resistance can reduce maintenance costs. In the installation of some decorative metal structures, such as stainless steel railings, curtain walls, etc., hexagonal stainless steel nuts and nuts are also widely used, which can not only ensure a firm connection, but also maintain a clean and beautiful appearance.
Electronic equipment: It is used in shell assembly and circuit board fixing of electronic products. Because it has a certain degree of electrical conductivity (stainless steel has a certain degree of electrical conductivity, but it is worse than copper and other metals), it can also play a role in some situations where grounding or electromagnetic shielding is required. At the same time, its corrosion resistance can prevent loose connections due to environmental factors and ensure the long-term stable operation of electronic equipment.
