M4 Internal External Thread Serrated Connection Component Prototype CNC Parts 30mm
M4 internal and external thread serrated safety equipment connection component CNC machining hardware
Materials and Processes: The Dual Advantages of National Standard Brass and Precision Machining
Material Properties of National Standard Brass
National Standard Brass (such as H62, H59, etc.), as the core material for these components, offers multiple advantages:
  • Excellent Machinability: Brass has good plasticity and low cutting resistance, making it highly suitable for precision machining operations
  • Good Electrical and Thermal Conductivity: This makes it perform exceptionally well in electrical connections and heat-dissipating components
  • Corrosion and Wear Resistance: It exhibits high stability in humid environments with mild corrosive media
  • Cost-Effectiveness: Compared to other copper alloys, National Standard Brass delivers superior cost advantages while maintaining performance
Technological Value of Precision Machining
The production of through-hole components with internal and external threads relies on mature precision machining processes:
  • High Precision and Consistency: Strict control over critical parameters such as thread accuracy, coaxiality, and perpendicularity
  • Complex Structure Capability: Can machine complex structures such as integrated internal and external threads, multiple steps, chamfers, and knurling
  • Customization Capability: Custom production according to specific drawings and international standards (ISO, DIN, ANSI)
Core Application Scenarios in International Manufacturing
Electrical and Electronic Equipment Manufacturing
  • Connectors and Terminal Components: Serving as internal thread bases for circular connectors and terminal blocks
  • Switches and Relays: Acting as conductive and structural support components inside precision switches and relays
Industrial Automation and Robotics
  • Pneumatic and Hydraulic Systems: As threaded joints in pneumatic components and hydraulic valve blocks
  • Robotic Arms and Actuators: Serving as adjustment and locking elements in precision motion components
Automotive and Rail Transportation
  • On-Board Electrical Systems: Used in the connection of components such as headlights, sensors, and ECUs
  • Brake and Fuel Systems: As pipeline joints guaranteeing sealing and reliability of fluid transmission
Medical Devices and Precision Instruments
  • Diagnostic and Therapeutic Equipment: Acting as structural connectors in medical devices
  • Measurement and Analytical Instruments: As adjustment and fixation elements in optical instruments and spectrometers
Shipbuilding and Offshore Engineering
  • Deck and Cabin Equipment: As corrosion-resistant threaded connectors in navigation and communication equipment
  • Underwater Equipment: Serving as sealing and connecting components in ROVs and underwater sensors
