Medical bone screw accessories are an essential part of orthopedic surgery, serving as crucial components in the fixation and stabilization of fractured bones. These accessories are engineered with high precision to ensure accurate alignment, optimal healing, and long-term performance. Used in trauma surgery, spinal procedures, maxillofacial reconstruction, and dental implantology, bone screw components must meet strict medical standards for biocompatibility, mechanical strength, and corrosion resistance.
Our medical bone screw accessories are manufactured using advanced CNC machining, precision grinding, and automated inspection to achieve consistent quality and meet ISO 13485 medical device regulations. Whether for permanent implants or temporary fixation, our products are designed to ensure surgical success and patient recovery.
Medical bone screw accessories include various supporting components such as screw heads, washers, locking plates, sleeves, and specialized fasteners. They work alongside bone screws to enhance stability, distribute load, and prevent loosening during healing.

Bone screw accessories are used across a wide range of surgical disciplines:
Trauma Surgery – Fixation of fractures in long bones such as the femur, tibia, and humerus.
Spinal Surgery – Stabilizing vertebral columns during correction of deformities or injury repair.
Craniofacial Surgery – Reconstructive procedures for the skull and facial bones.
Orthognathic Surgery – Jaw realignment and dental restoration.
Sports Medicine – Repairing ligament and tendon attachment points.
Our production process ensures high precision, repeatability, and compliance with medical standards:
Material Selection & Certification – Sourcing titanium, stainless steel, or bioabsorbable polymers from certified suppliers.
Precision CNC Machining – Using 5-axis milling and Swiss-type turning for complex geometries.
Thread Rolling & Grinding – Achieving uniform pitch and depth for stable fixation.
Surface Finishing & Coating – Applying anodizing, passivation, or HA coating as required.
Quality Inspection – 100% dimensional verification using coordinate measuring machines (CMM).
Cleaning & Sterilization – Ultrasonic cleaning and sterile packaging in ISO Class 7 cleanrooms.
To ensure the highest quality and precision for medical bone screw accessories, we operate with state-of-the-art production machinery, including:
5-Axis CNC Machining Centers – Capable of producing complex shapes with ultra-tight tolerances.
Swiss-Type CNC Lathes – For micro-sized components with perfect concentricity.
Automated Optical Inspection Systems – Detecting microscopic defects.
Coordinate Measuring Machines (CMM) – Ensuring dimensional consistency across every batch.
Ultrasonic Cleaning Systems – For contaminant-free surfaces before sterilization.
Our advanced equipment setup enables high-volume production without compromising precision, ensuring every accessory meets stringent medical standards.
