Knurled Long Screw Assemblies: Applications in Medical Industry (Product‑specific), Features & Export Standards by Country

1. Applications in the Medical Industry (Specific Products)

1.1 Life Support & Monitoring Equipment

Patient monitors / ECG machines: Knurled long screw assemblies (M2.5–M6) used for enclosure fastening, display bracket adjustment, and keypad panel fixation, providing stable, vibration-resistant threaded connections for repeated assembly and disassembly.
Ventilators / anesthesia machines: Knurled long screws for gas circuit modules, control panel mounting, and tubing bracket fixation, compatible with medical-grade PC/ABS materials, anti-loosening, corrosion-resistant and easy to clean and disinfect.
Infusion pumps / syringe pumps: Knurled long screw assemblies used in transmission mechanisms, housing assembly, and battery compartment locking, ensuring long-term operational stability and compliance with medical cleaning and sterilization requirements.

1.2 Surgical & Diagnostic Instruments

Endoscopes / laparoscopes: Precision knurled long screws (M1.6–M3) for handle assembly, housing connection, and optical component adjustment, with dimensional tolerance ±0.02 mm, suitable for repeated sterilization and aseptic environments.
Surgical instruments (forceps, scissors, scalpel handles): Knurled long screws for connecting plastic handles and metal components, featuring high‑grip knurling to prevent rotation and slippage, compatible with autoclave sterilization.
Ultrasound scanners: Knurled long screw assemblies for probe interfaces, control panel assembly, and support bracket fixation, ensuring reliable mechanical connection and good EMC performance.

1.3 Rehabilitation & Orthopedic Devices

Prosthetics / orthotics: Knurled long screws (M4–M8) for joint adjustment, brace assembly, and mechanism locking, lightweight, high‑strength, ergonomic and suitable for long-term wearing.
Wheelchairs / walkers: Knurled long screw assemblies for armrest, footrest and backrest adjustment, impact-resistant, anti-loosening, and suitable for frequent position changes.

1.4 Medical Consumables & Laboratory Equipment

Disposable syringes / blood collection needles: Micro knurled long screws for needle hub and plunger assembly, ensuring high assembly accuracy and operational safety.
Incubators / centrifuges: Knurled long screws for housing, door and rotor mounting, resistant to high and low temperatures, humidity and chemical disinfection.

2. Key Features of Medical‑Grade Knurled Long Screw Assemblies

2.1 Material Properties (Medical Requirements)

Material: Medical‑grade lead‑free brass or stainless steel, compliant with RoHS, REACH and FDA food‑contact standards, lead content ≤ 0.05%.
Biocompatibility: Tested and certified in accordance with ISO 10993 (cytotoxicity, irritation, sensitization), safe for direct or indirect contact with human tissue and body fluids.
Corrosion resistance: No rust or harmful precipitation in disinfection environments such as iodophor, alcohol and EO sterilization; salt spray test ≥ 48–1000 hours according to grade.
Material stability: Stable performance under repeated high-temperature sterilization and long-term use.

2.2 Structural & Processing Advantages

Knurling design: Straight knurling, diamond knurling or helical knurling provides high friction and anti‑slip performance, effectively preventing rotation and loosening during adjustment.
High precision: Thread tolerance 6H, dimensional tolerance ±0.02–0.05 mm, ensuring assembly consistency and interchangeability.
Surface treatment: Passivation, lead-free nickel plating or environmental passivation, free of harmful substances, meeting medical export requirements.
Mechanical performance: High tensile strength, excellent torque resistance and fatigue resistance, suitable for long-term dynamic use.

2.3 Medical Application Requirements

Cleanliness: Produced in Class 7–8 cleanrooms, free of burrs, oil stains and metal particles.
Sterilization compatibility: Resistant to autoclaving (121 °C / 0.1 MPa), ethylene oxide (EO) sterilization and low-temperature plasma sterilization.
Reliability: Stable performance after ≥ 100 assembly and adjustment cycles, designed for a service life of 5–10 years in medical devices.
