  • Patient monitors / ECG machines: Brass knurled nuts (M2.5-M6) used as heat‑insert or injection‑molded inserts for enclosures, display brackets, and keypad panels
  • Ventilators / anesthesia machines: Knurled brass inserts for gas modules, control panels, and tubing mounts
  • Infusion pumps / syringe pumps: Knurled brass nuts used in transmission mechanisms, housings, and battery compartments
Surgical & Diagnostic Instruments
  • Endoscopes / laparoscopes: Precision knurled nuts (M1.6-M3) for handles, endoscope housings, and optical component mounts
  • Surgical instruments (forceps, scissors, scalpel handles): Inserts connecting plastic handles and metal parts
  • Ultrasound scanners: Brass knurled nuts for probe interfaces, control panels, and brackets
Rehabilitation & Orthopedic Devices
  • Prosthetics / orthotics: Knurled nuts (M4-M8) for joints, braces, and adjustment mechanisms
  • Wheelchairs / walkers: Fastening inserts for armrests, footrests, and backrests

  • Incubators / centrifuges: Knurled inserts for housings, doors, and rotor mounts

Key Features of Medical‑Grade Brass Knurled Nuts
Material Properties (Medical Requirements)
  • Material: Preferred lead‑free brass (C3604, lead‑free H62), compliant with RoHS, REACH, and FDA standards
  • Biocompatibility: Certified according to ISO 10993 (cytotoxicity, irritation, sensitization)
  • Corrosion resistance: No rust or hazardous leaching in disinfection environments
  • Thermal conductivity: Suitable for heat‑insertion or ultrasonic insertion
Structural & Processing Advantages
  • Knurling design: Straight, diamond, or double‑helix knurling creates mechanical interlocking
  • Precision: Thread tolerance 6H, dimensional tolerance ±0.02-0.05 mm
  • Surface treatment: Passivation, lead‑free nickel plating, or environmental passivation
  • Process compatibility: Compatible with heat insertion, hot pressing, ultrasonic welding, and injection molding
Medical Application Requirements
  • Cleanliness: Produced in Class 7-8 cleanrooms, free of burrs, oil, and metal particles
  • Sterilization compatibility: Resistant to autoclaving, ethylene oxide, and low‑temperature plasma sterilization
  • Reliability: Stable after ≥ 100 assembly cycles, designed for 5-10 years service life

Export Standards for Medical Hardware
Global General Standards
  • Quality management system: ISO 13485 (mandatory for medical devices worldwide)
  • Biocompatibility: ISO 10993 series (essential for patient‑contact components)
  • Environment & hazardous substances: RoHS 2.0, REACH compliance
  • Traceability: UDI (Unique Device Identification), batch code, material, sterilization and certification marks
