A nut is a component that is screwed together with a bolt or screw rod to play a fastening role. It is a commonly used element in all manufacturing machinery. It connects with bolts of the same specification through the internal threads to achieve a tight connection of mechanical equipment.
Low cost, adjustable strength, used for ordinary building and simple mechanical connections.
Corrosion-resistant and attractive. Ideal for food, chemical, and medical industries.
Excellent electrical and thermal conductivity. Used in electrical and heat dissipation equipment.
High strength and toughness. Optimized via heat treatment for aerospace and automotive industries.
| Specification Types | Details |
|---|---|
| Thread (Metric) | Starts with "M", followed by nominal diameter (e.g., M4, M6). |
| Thread (Imperial) | Using inches, consists of outer diameter and threads per inch (e.g., 5/16 - 18UNC). |
| Across Flats Distance | Closely related to thread specification; designed to fit standard wrench operations. |
| Nut Thickness | Determined according to the specific size of the bearing load. |
| Hexagon Nuts | Widely used in automobile manufacturing, mechanical equipment, and building structures. Withstands large tensile and shear forces. |
| Lock Nuts | High reliability for aerospace, railway transportation, and precision machinery. Prevents loosening under vibration. |
| Wing Nuts | Butterfly shaped for manual tightening. Used in furniture, toys, and instruments requiring frequent adjustment. |
| Flange Nuts | Increases contact area for improved stability and sealing. Used in pipeline connections and pressure vessels. |
| Weld Nuts | Fixed by welding for fast, reliable connections in electronic equipment and automotive production. |
