The Micro-Fix MTD-100 Eddy Current Tapped Hole Inspector is a high-performance Non-Destructive Testing (NDT) instrument specifically engineered to detect internal cracks, surface flaws, thread damage, and structural imperfections inside tapped holes. In precision manufacturing sectors—such as engine block fabrication, transmission housings, aerospace structures, automotive safety components, and pressure vessels—micro-cracks formed during tapping operations are virtually impossible to identify through visual inspection or mechanical thread gauges. Unidentified defects can result in catastrophic structural failure under high mechanical stress during operation.

Operating on high-sensitivity Eddy Current Testing principles, the Micro-Fix MTD-100 induces electromagnetic eddy currents into the conductive walls of the tapped hole via specialized inspection probes. Any interruption caused by cracks or geometric thread anomalies alters the impedance signal, which is instantly processed by the system. Clear Pass/Fail indicators streamline QA/QC procedures directly on production lines.

Designed for maximum reliability and versatility, the MTD-100 supports both manual handheld inspection and integration into fully automated robotic testing stations. Accommodating a wide range of interchangeable probe sizes, it ensures zero-defect quality control across diverse hole diameters and thread pitches.
