Fully Threaded Cortical Screw

316LVM Stainless Steel Locking Screw Overview & Manufacturing Precision

At Xiamen Dazao Machinery, we manufacture medical orthopedic stainless steel locking screws specifically engineered for high-load fracture fixation. By utilizing advanced CNC stainless steel machining and Swiss-type turning, we ensure that every screw head integrates perfectly with locking plates. This creates a rigid internal fixator system, essential for treating osteoporotic bone or complex comminuted fractures. Our 316LVM vacuum-melted steel guarantees maximum fatigue resistance and minimizes metallic ion release in vivo.

Fully Threaded Cancellous Screw

Engineering Specifications: ISO 5832-1 Compliant Parameters

Using structured custom CNC machining services, we produce screws that meet the following rigorous technical standards:

Technical Attribute	Specification Detail
Material Standard	Implant Grade 316LVM (ASTM F138 / ISO 5832-1)
Diameter (Ø)	1.5mm, 2.0mm, 2.4mm, 2.7mm, 3.5mm, 4.0mm, 5.0mm, 6.5mm
Length Range	6mm to 150mm (Customizable in 1mm increments)
Head Interface	Tapered Locking Thread (Star/Torx or Hexagonal Drive)
Thread Geometry	Cancellous, Cortical, or Full-thread Self-tapping
Surface Finish	Ra 0.4 μm (Mirror Polished & Passivated)
Concentricity	≤ 0.02mm (Total Indicator Run-out)

Tapered Thread Design for Angular Stability

The locking head features a precision-machined conical thread. When engaged with a bone plate, it forms a monolithic structure that prevents screw back-out and maintains reduction under physiological loading.

Self-Tapping & Self-Drilling Tip Geometry

Our CNC-milled flutes are sharpened to surgical-grade requirements, allowing for direct insertion without pre-tapping, preserving bone stock and reducing thermal necrosis risks.

Double-Thread Iocking Screw for Plates

ISO 13485 Quality Control & CMM Inspection Protocols

Our quality inspection department executes a zero-defect policy for all orthopedic implants stainless steel screws:

Raw Material Validation: Spectrographic analysis to confirm 316LVM chemistry.

CMM Dimensional Audit: Automated coordinate measuring machines verify thread pitch and lead accuracy.

Torque Strength Testing: Destructive and non-destructive testing to ensure compliance with ASTM F543 requirements.

Cleanroom Processing: Final cleaning and primary packaging in Class 10,000 (ISO 7) environments.

Cannulated Compression Screw

FAQs

Headless Cannulated Compression Screw With Variable-Pitch Thread

01.Why choose 316LVM over standard 316L for orthopedic locking screws?

316LVM (Low Carbon Vacuum Melt) undergoes a secondary melting process to eliminate impurities. This results in a cleaner microstructure with higher fatigue strength and better corrosion resistance, which is mandatory for long-term orthopedic implants stainless steel screws.

02.What are the advantages of self-tapping stainless steel orthopedic screws?

Self-tapping screws feature a cutting flute at the tip that creates its own thread during insertion. This eliminates the surgical step of tapping, reduces the duration of anesthesia, and provides a tighter thread-to-bone interface for better initial stability.

03.Can you manufacture custom made orthopedic stainless steel screws for proprietary plate systems?

Yes. We specialize in OEM production. By providing your 3D CAD files (STEP/IGS), we can customize the head taper angle, thread pitch, and drive type to ensure 100% compatibility with your existing locking plate inventory.

04.How do you handle the passivation process for medical-grade screws?

All screws undergo nitric or citric acid passivation per ASTM A967. This process removes exogenous iron from the surface and enhances the passive chromium oxide layer, ensuring the screws remain inert in the human body's corrosive saline environment.

05.What is the typical lead time for bulk stainless steel orthopedic locking screws?

For standard sizes (e.g., 3.5mm cortical locking screws), we maintain a semi-finished stock, allowing delivery within 7-10 days. For custom OEM orders, mass production typically takes 15-25 days depending on the complexity and volume.

06.Are your screws compatible with FDA approved stainless steel locking screws standards?

Yes. Our manufacturing processes and material sourcing are fully compliant with FDA and CE regulatory requirements. We provide full documentation, including Material Mill Certificates, COA (Certificate of Analysis), and FAI (First Article Inspection) reports.
