Coupling Nut
Products Description
Coupling nuts are double-sided, fully internally threaded, straight-through steel fasteners primarily used for extending, spacing, and coaxially rigidly connecting two externally threaded rods or bolts. They provide an integrated threaded connection solution for various mechanical assembly, frame construction, and tooling fixing scenarios.
This product belongs to the Metal Steel Screw Hardware Fasteners system and is compatible with most metric coarse and fine thread systems. It perfectly matches the engineering assembly needs of multi-component link splicing, distance extension, and structural reinforcement in system integration projects, ensuring the connection compatibility and long-term operational stability of the entire assembly system from the bottom layer of the solution.
Product Details and Features
Precision Internal Threads
The Hex Jam Nut features continuous internal threads at both ends, with complete tooth profiles and no broken or missing teeth. Precise thread tolerance control ensures smooth, non-jamming engagement. The screw connection is coaxial and concentric throughout, guaranteeing dimensional accuracy in the assembly process.
Standard Shape and Structure
The Self-locking Nut features a standard industrial hexagonal shape. The wrench gripping surface is flat, ensuring even force distribution and preventing slippage. It is compatible with most standard sockets and open-end wrenches on the market, eliminating compatibility barriers and adapting to common on-site construction conditions in integrated projects.
Extended Structural Design
The axial length is significantly greater than that of conventional nuts, effectively extending the thread engagement length, increasing the connection and tightening force, distributing axial tensile loads, and suppressing thread loosening and displacement under vibration.
End Face Chamfering
Both ends of the Slotted Castle Nut undergo deburring and chamfering, ensuring smooth screw insertion without sharp edges scratching the thread plating and tooth profile, protecting the integrity of the threads of the matching bolts and screws throughout the process.
Core Material Advantages
| Carbon Steel Substrate Advantages | Belonging to the Metal Steel Screw Hardware Fasteners category, it boasts a stable raw material supply, sufficient mechanical toughness, high cost-effectiveness, and comprehensive coating protection, making it suitable for most conventional integrated project scenarios such as indoor general machinery, steel structure frames, and equipment racks. |
| Stainless Steel Substrate Advantages | Belonging to the Stainless Steel Fasteners category, it is a high-end corrosion-resistant material with no risk of additional coating peeling. It possesses excellent inherent resistance to oxidation and acid/alkali corrosion, and no harmful substances are released, making it suitable for system integration applications with high corrosion resistance requirements, such as food machinery, medical devices, outdoor engineering, and chemical equipment. |
