Brass Knurled Nuts: Applications in Medical Industry
Applications in the Medical Industry
Life Support & Monitoring Equipment
- 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
Medical Consumables & Laboratory Equipment
- Disposable syringes / blood collection needles: Micro knurled brass nuts for needle hubs and plungers
- 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
