Direct-from-factory micro-fixation hardware manufactured with sub-micron Swiss CNC tolerances (±0.005mm) for trauma, orthopedic, and pediatric surgical applications.
In rigid internal fixation (RIF) and craniomaxillofacial (CMF) surgical procedures, structural integrity, biomechanical stability, and tissue compatibility are paramount. As a premier **China wholesale micro craniofacial screws factory and OEM supplier**, our production ecosystem bridges state-of-the-art metallurgical science with ultra-precision CNC Swiss sliding head lathe machining. Micro craniofacial screws—spanning thread diameters from **M1.2, M1.4, M1.5, M1.6, M1.7 to 2.0mm and 2.5mm**—are purpose-built to immobilize bone fragments, anchor micro titanium plates, and reconstruct complex pediatric or adult cranial defects.
The anatomical constraints of the human skull, periorbital rim, zygomatic arch, and mandible require micro screws that minimize soft-tissue palpability while maximizing retention torque. Whether utilizing **Self-Tapping** or **Self-Drilling** flutes, micro bone screws must enter dense cortical bone without generating excessive frictional heat, which risks localized thermal osteonecrosis. Our cleanroom-manufactured micro screws feature specialized fluted tip profiles and proprietary surface passivation treatments that facilitate effortless bone penetration and long-term osseointegration.
Extra Low Interstitial (ELI) Grade 5 titanium represents the pinnacle material for permanent CMF implants. Offering exceptional strength-to-weight ratio, non-magnetic MRI compatibility, and superior biocompatibility, titanium alloy forms an inert titanium dioxide surface film ($TiO_2$) upon exposure to air, shielding the implant from bodily fluid corrosion.
Vacuum Melted (LVM) Stainless Steel provides maximum ductility, high fatigue endurance, and cost-efficient performance for temporary fixation, maxillofacial trauma kits, and veterinary instruments. SS316L micro screws are meticulously electropolished to eliminate microscopic surface fissures.
| Screw System Size | Thread Diameter (mm) | Core Diameter (mm) | Head Diameter (mm) | Typical Drive Mechanism | Primary Surgical Indication |
|---|---|---|---|---|---|
| Micro 1.2 System | 1.20 mm | 0.85 mm | 2.00 mm | Cross-Slot / Hex 0.9 | Pediatric Cranial, Naso-Ethmoid-Orbital (NEO) Fixation |
| Micro 1.5 / 1.6 System | 1.50 - 1.60 mm | 1.10 mm | 2.30 mm | Square Drive / Hex 1.2 / Torx | Midface Trauma, Cranial Vault Reshaping, Orthognathics |
| Mini 2.0 System | 2.00 mm | 1.45 mm | 3.00 mm | Hex Slot / Star Drive | Mandibular Reconstruction, Sagittal Split Osteotomy |
| Emergency 2.3 / 2.5 System | 2.30 - 2.50 mm | 1.80 mm | 3.50 mm | Self-Tapping Hexagon | Rescue Screw for Stripped Bone Threads in CMF Surgery |
Global clinical preferences are rapidly transitioning from traditional self-tapping screws toward **self-drilling micro screws**. By integrating sharp cross-cutting flutes into the screw tip, surgeons eliminate the preliminary pilot drilling step, reducing operating room time, minimizing bone debris generation, and reducing thermal risk.
Hospitals and surgical procurement teams are demanding color-coded anodized micro screws (Pink, Blue, Gold, Green) for immediate intraoperative system identification. Advanced Type II and Type III anodization improves surface hardness, reduces friction, and enhances fatigue resistance under cyclic masticatory forces.
While metallic titanium remains the gold standard for load-bearing mandibular areas, pediatric cranial surgery is seeing increased interest in magnesium-alloy and PLLA bioabsorbable screws. Direct-from-factory suppliers are now bundling customizable, 3D-printed titanium mesh plates with pre-matched micro screw sets.
As a vertically integrated medical hardware manufacturer, our production facility houses multi-axis CNC automatic sliding head machines (Citizen & Star Swiss Lathes), high-speed Vertical Machining Centers (VMC), and cleanroom packaging facilities. We eliminate intermediary markups, offering direct OEM/ODM wholesale supply to global medical device distributors, brand owners, and hospital networks.
Equipped with ultra-precise Swiss automatic sliding head lathes capable of turning micro screws down to M1.2 with thread tolerances controlled within 0.005mm. Flutes and drive slots (Cross, Hex, Square, Torx) are burr-free under 50x optical inspection.
Operating under strict ISO 13485:2016 quality management systems. Every batch undergoes 100% optical sorting, coordinate measuring machine (CMM) dimensional verification, destructive torque testing, and ultrasonic passivation cleaning.
We support custom head geometries, non-standard thread pitches, dedicated surgical tray sets, and custom branding for international OEM clients. Engineering samples delivered in as fast as 7-10 business days.
When sourcing micro craniofacial screws from China factories, procurement directors and medical device buyers must evaluate five fundamental technical metrics to ensure clinical compliance and avoid regulatory friction:
Demand chemical analysis and mechanical testing certificates per ASTM F136 (Titanium Grade 5 ELI) or ASTM F138 (SS316L) for every single raw material ingot batch. Our factory provides 100% lot-traceable heat numbers with every shipment.
Micro bone screws operate under high rotational torque during insertion into dense cortical bone. Our in-house testing lab validates insertion torque, removal torque, and ultimate torsional breaking force to guarantee zero intraoperative screw head shearing.
Post-machining residual oils, metallic micro-particles, and carbon contaminants are completely removed using multi-stage ultrasonic bath cleaning, citric acid passivation, and Grade 100,000 cleanroom packaging readiness.
Supplied in non-sterile bulk B2B packaging or pre-validated Tyvek peelable pouches compatible with Gamma Ray, ETO (Ethylene Oxide), or Autoclave steam sterilization protocol validation.
