Description of Rolled Copper Nut: Discover the incredible versatility and robustness of our rolled copper nuts, crafted to perfection for superior performance.
1, Product Definition and Core Features: Unveiling the essence and standout attributes of our innovative copper fasteners.
Rolled Copper Nut: Our premium fasteners are crafted using high-grade copper alloy, such as H62 brass or C3604 lead brass, characterized by excellent conductivity, corrosion resistance, and remarkable anti-loosening capabilities. These nuts are precisely formed through cold heading and machining, and are skillfully rolled with straight or mesh patterns on the surface, making them indispensable in electronics, machinery, and automotive industries. The core design logic integrates:
• Roll Pattern Structure: Our engineers employ advanced physical extrusion to create tooth-shaped patterns with a depth of 0.05-0.2mm, significantly enhancing frictional resistance and adhesion to substrates.
Copper-Based Characteristics: By harnessing copper's exceptional conductivity (≥ 58MS/m) and corrosion resistance (salt spray test ≥ 72h), our rolled copper nuts are the perfect choice for precision equipment applications.

Hardness: Engineered with a hardness of HB80-120 in the annealed state, our thin plates are crafted to prevent substrate damage during installation.
Thread Specifications: Available in M2-M10 (metric) and 4-40UNC (imperial) sizes, our nuts excel in PCB board and sensor bracket fixing applications.
Roll Pattern Type: Choose from straight grain (120°), mesh pattern (diamond cross) designs, perfectly suited for vibration environments, ensuring secure shaft connections.
Surface Treatment: With options like nickel plating (Ni ≥ 5 μm), passivation, and natural polishing, our treatments prevent oxidation and meet stringent conductivity requirements.
2. Structural Innovation Points: Explore our groundbreaking engineering enhancements that redefine performance standards.
Double End Embossing Design: Featuring an innovative design with one end embossed and the other chamfered, our nuts provide balanced anti-loosening and precision guiding functions (e.g., M3 × 0.5 nuts, chamfered at 15°).
Thin Wall Strengthening Process: Through cold extrusion, our process achieves a thicker wall structure (from 0.8mm to 1.2mm), significantly boosting torsional strength (≥ 15N·m).
3, Application Scenarios and Selection Logic: Discover the tailored applications of our rolled copper nuts and the strategic approach to selecting the ideal solution.
1. Typical Application Scenarios: Our copper nuts excel across various industries, providing reliable and efficient solutions.
Electronic Devices: Securely affixes phone frames to PCB boards using M2 × 0.4 embossed copper nuts, featuring nickel plating to prevent oxidation.
Automotive Industry: Ideal for connecting sensors to metal brackets with M4 × 0.7 mesh roller patterns, these nuts withstand high temperatures up to 150°C.
Precision Instrumentation: Our M2.5 × 0.45 straight line rolled nuts ensure low friction (≤ 0.15) for optical lens focusing ring applications.
2. Three Step Selection Method: A systematic approach to ensure the perfect match for your application needs.
Step 1: Substrate Matching: Choose the optimal embossing and material state to complement your substrate and prevent damage.
Soft Plastic (e.g., PC): Opt for straight grain embossing in an annealed state (hardness HB80) to prevent cracking and ensure stability.
Metal Substrate (e.g., Aluminum Alloy): Select mesh rolling with nickel plating to enhance corrosion resistance and longevity.
Step 2: Load Verification: Ensure reliability through rigorous tensile and dynamic load testing.
Static Load: Our single M3 knurled copper nuts boast a tensile strength of ≥ 300N, as verified by comprehensive measurements.
Dynamic Load: Capable of withstanding over 2000 cycles of vibration testing (10-55Hz, 1.5mm amplitude) without loosening, ensuring long-lasting durability.
