Torque - to - Failure Tester for Metal Bone - connecting Screws
The Torque-to-Failure Tester for Metal Bone-Connecting Screws is designed to evaluate the torsional strength and mechanical failure characteristics of metallic bone screws used in orthopedic implants. By applying controlled rotational force to a screw, the tester measures the torque required to cause yielding or fracture and can record the breaking angle.
The test results help assess the mechanical properties of bone screws, compare different materials and designs, and support product development and manufacturing quality control. The testing system can incorporate a torque sensing system, force sensor, angle sensor, and appropriate clamping fixtures to evaluate screw performance under specified test conditions.
