Torque-to-Failure Tester for Metal Bone-Connecting Screws is a specialized device designed to measure the maximum torque a metal orthopedic screw can withstand before failure. It evaluates the mechanical strength, torsional resistance, and safety of bone screws used in surgical fixation. This tester is widely used in R&D, quality control, and regulatory testing to ensure screws meet performance standards and prevent implant failure during orthopedic procedures.
Standard
(1)YY/T 0662-2008(Chinese standard for orthopedic implant testing)
(2)ISO 5832-1(Metallic materials for surgical implants – Wrought stainless steel)
(3)ASTM F543(Standard specification for metallic medical bone screws)
(4)ISO 6475(Breaking torque and angle of rotation at failure for metal bone screws)
(5)EN ISO 14708-1(Active implantable medical devices – General safety requirements)
Product Advantages
(1)Multi-Standard Compliance: Seamlessly aligns with ASTM, ISO, and EN standards, enabling global market access.
(2)High-Precision Torsional Testing: Capable of measuring breaking torque and rotational angles with ±0.1% accuracy, critical for evaluating screw uniformity.
(3)Versatile Testing Modes: Supports torsional-only and axial-torsional combined loading (up to 17.750 in-lb torque capacity) for comprehensive material characterization.
(4)User-Friendly Interface: Intuitive software with real-time data logging, test customization, and automated report generation (PDF/Excel formats).
(5)Durability: Robust construction with corrosion-resistant components, ideal for repetitive high-load testing in medical device labs.
Product Features
(1)Torque Capacity: 62–17.750 in-lb (0.7–2000 Nm), covering small-diameter screws to heavy-duty implants.
(2)Rotational Speed: 0.001°–360°/min, adjustable for static or dynamic failure analysis.
(3)Axial-Torsional Synchronization: Optional biaxial loading for simulating complex surgical insertion forces (per ASTM F543’s full test suite).
(4)Collet-Style Grips: Non-slip, specimen-friendly clamping to prevent premature failure or specimen damage.
(5)Biomechanical Simulation: Compatible with rigid polyurethane foam (ASTM F1839) and natural bone substitutes for self-tapping/driving tests.
(6)Safety Systems: Emergency stop, overload protection, and automatic specimen ejection.
Accessories (Included/Optional)
(1)Standard Kit:
Collet grips (4 mm–8 mm diameter range)
Rigid polyurethane foam blocks (ASTM F1839-compliant)
Calibration certificate (ISO 17025 accredited)
Test control software (multi-language support)
(2)Optional Upgrades:
Axial-torsional load frame (for combined loading tests)
High-temperature chamber (for thermal stability testing)
Automated specimen feeder (high-throughput labs)
Custom collet sets (for miniature or oversized screws)
