Vibration-Resistant Custom Brass Threaded Fastener – Engineered for Medical Devices & Industrial Automation

Scene-Specific Technical Values

1. Vibration-Proof Performance Breakthrough

   
   

   Built with a triple-lock thread profile (patent-pending), this fastener maintains 98% clamping force after 10,000 cycles of high-frequency vibration (10–2000 Hz) — a 65% improvement over standard brass fasteners. This makes it indispensable for industrial automation robots, where persistent vibration often causes loose connections and equipment downtime.
2. Medical-Grade Material & Hygiene Compliance

   
   

   Crafted from medical-certified brass alloys (C2680/CW508L), the fastener meets ISO 10993 biocompatibility standards and withstands repeated exposure to harsh disinfectants (e.g., ethanol, hydrogen peroxide) without surface degradation. It also undergoes a passivation treatment that reduces bacterial adhesion by 70%, ideal for diagnostic equipment and surgical tools requiring strict hygiene control.
3. Extreme Environment Adaptability

   
   

   Tested to perform reliably across a temperature range of -50℃ to 180℃ (far exceeding the -40℃ to 150℃ range of standard brass), the fastener resists thermal expansion/contraction-related loosening. Its enhanced brass composition also achieves a 50% higher tensile strength (up to 450 MPa) and passes 600-hour neutral salt spray testing (per ASTM B117) — suitable for outdoor industrial sensors and marine automation systems.

Material & Manufacturing Innovations

• Base Alloy Selection: Medical-grade C2680 (high ductility) or industrial-grade CW508L (high strength) brass, selected based on application needs. Both alloys undergo grain refinement treatment to reduce internal stress and prevent cracking under cyclic loads.
• Machining Technology: Adopts 5-axis CNC machining (vs. traditional 3-axis) to achieve ultra-precise alignment between the head notch and central pin (tolerance ≤0.005mm), ensuring seamless integration with custom fixtures in automated assembly lines.
• Surface Treatment: A dual-layer coating (electroless nickel + clear passivate) that enhances corrosion resistance while maintaining electrical conductivity — critical for medical devices requiring both hygiene and grounding functionality.

Industry-Specific Custom Solutions

1. Medical Device Customization

• Offers autoclavable versions (compatible with 134℃ steam sterilization cycles) for surgical robots and patient monitors.
• Provides laser-engraved part numbers for full traceability (per FDA 21 CFR Part 820) to meet medical regulatory requirements.

2. Industrial Automation Adaptations

• Supports custom thread lengths (5mm–100mm) and head styles (pan, countersunk, hex) for robotic arm joints and conveyor system components.
• Includes a pre-applied anti-seize compound (PTFE-based) to prevent thread galling during high-torque installation in heavy-duty machinery.

Quality Assurance & Service Commitments

• Testing Protocols: Each unit undergoes vibration testing (per IEC 60068-2-6), chemical resistance testing (per ISO 10993-10), and dimensional inspection (via 3D laser scanning) to ensure compliance with industry standards.
• Traceability System: Full material lot tracking from raw brass ingot to finished product, with detailed inspection reports provided for every order.
• Logistics & Support: Offers sterile packaging for medical orders (compliant with ISO 11607) and just-in-time (JIT) delivery for industrial automation clients. Provides 24/7 technical support for custom design adjustments.
