Medical Industry Applications
Life Support & Monitoring Equipment
  • Neonatal incubators & infant warmers: Knurled nuts used for panel fixing, adjustment mechanism locking, and component assembly, providing stable anti‑slip fastening.
  • Anesthesia machines & ventilators: Used in gas circuit modules, control panels, and internal structural parts for reliable fixation under vibration and repeated disinfection.
  • Patient monitors & portable ultrasound devices: Anti‑rotation and anti‑slip knurled nuts for internal bracket assembly, PCB fixing, and module positioning.
Surgical Instruments & Minimally Invasive Devices
  • Laparoscopic / endoscopic instruments: Knurled nuts for handle components, instrument body assembly, and adjustable parts, enabling easy manual tightening without tools.
  • Orthopedic & dental instruments: Used in surgical drills, handpieces, and implant tools for quick assembly and firm locking.
  • Surgical robot arms: High‑precision knurled nuts for joint assembly and fine‑tuning structures, ensuring stable positioning in narrow spaces.
Diagnostic & Laboratory Equipment
  • Biochemical analyzers & hematology analyzers: Knurled nuts for sampling mechanisms, reagent trays, and pump components, ensuring stable connection during high‑frequency movement.
  • CT / MRI equipment: Non‑magnetic stainless steel knurled nuts for internal shielding and platform fixing, avoiding interference with imaging systems.
Rehabilitation & Assistive Devices
  • Rehabilitation robots & exoskeletons: Used in limb joint adjustment and modular assembly for reliable, tool‑free locking.
  • Orthopedic braces & prosthetics: Knurled nuts for size adjustment and component fixing, with good biocompatibility and comfort.
Key Characteristics
  • Excellent anti‑slip & anti‑rotation performance: Straight knurling design provides high friction for stable manual tightening.
  • High precision & consistent fit: Stable thread accuracy ensures reliable assembly and interchangeability.
  • Medical‑grade materials: Mainly 316 / 316L stainless steel, with good corrosion resistance and biocompatibility, meeting ISO 10993 requirements.
  • Sterilization resistant: Withstands autoclaving, EO sterilization, alcohol, and disinfectants without rust or precipitation.
  • Hygienic & easy to clean: Smooth surface, no dead ends, suitable for medical clean environment.
  • High strength & durability: Stable under long‑term use, vibration, and repeated assembly/disassembly.
Manufacturing Advantages
Stable Knurling Quality & High Precision
Cold heading forms uniform, clear knurling with consistent texture. Precision machining ensures accurate thread size and fit.
Mass Production Consistency & Stability
Cold heading provides stable dimensions, grain structure, and mechanical properties. Reduces deformation and ensures reliable performance in medical devices.
Cost Efficiency for Medical Fasteners
Cold heading + precision machining reduces material waste and processing time. Balances high medical quality and competitive cost.
Medical‑Grade Surface Quality
Supports passivation, electropolishing, and cleaning to meet medical cleanliness standards. Burr‑free, crack‑free, low contamination risk.
Customization for Medical Devices
Customizable knurl type, thread size, length, and head shape. One‑stop solution from design to mass production.
