Linear Knurled Nut
Products Description
As a core component in mechanical connections, the Linear Knurled Nut utilizes a precision knurling process to create linear teeth on a cylindrical surface, providing an excellent coefficient of friction and grip. It allows for tool-free fastening, significantly improving anti-rotation and anti-slip performance during assembly. Compared to traditional hexagonal nuts, its knurled structure achieves high-friction grip without tools, making it specifically designed for high-vibration and micro-motion conditions. It is suitable for permanent fastening in electronic instruments, automated equipment, and precision machinery.
Product Features and Functions
Ergonomic Design
The knurled Jam Nut features a straight-knurled design with parallel knurling at a pitch of 0.5-1.0mm. Compared to diamond knurling, the straight-knurled structure provides stronger axial guidance and stability, making it particularly suitable for applications requiring frequent position adjustments. The knurling height is strictly controlled between 0.2 and 0.4mm to ensure a comfortable grip and prevent hand injury.
Self-Locking Anti-Loosening Mechanism
The knurled Locking Nut achieves a thread fit accuracy of 6H/6g. Combined with nylon inserts or a metal deformation locking structure, it maintains its preload without diminishing under vibration. Test data shows that under random vibration conditions of 5-2000Hz, the loosening torque retention rate is ≥85%.
Manufacturing Process
Cold Forging
The wire is cold-forged into the prototype of the knurled threaded nut using a high-pressure die, ensuring a dense internal grain structure and improved strength.
Knurling
High-precision knurling tools are used to press straight lines onto the surface, with the texture depth controlled between 0.1-0.3mm, balancing friction and appearance.
Heat Treatment
Knurled Bolt Nuts undergo quenching and tempering to ensure wear resistance.
Surface Treatment
Knurled Brass Nuts retain their original color or are polished; steel nuts are available with galvanizing (salt spray test ≥48 hours) or Dacromet coating.
Material Core Advantages
| Conductivity and Interference Resistance | Brass has high conductivity, ensuring low grounding impedance for Plain Knurled Nuts in electronic devices. It provides non-ferromagnetic EMI shielding, making it suitable for precision instruments. |
| Corrosion Resistance | Naturally corrosion-resistant, Knurled Washer Nuts can be used long-term without plating, suitable for high-cleanliness environments such as medical and food processing. |
| Machining Advantages | Soft and easy to machine, with precise knurled threads, self-lubricating torque reduction, and anti-seize properties, improving assembly efficiency of Knurled Hex Nuts. |
| Antibacterial and environmentally friendly | Copper ions inhibit bacteria, meet medical standards, and the Straight Knurled Nut is non-toxic and recyclable, meeting strict environmental and safety regulations such as RoHS and REACH. |
