The Micro-Fix NT-1 Tapped Hole Inspector is a high-precision specialized quality inspection system engineered to rapidly and accurately detect internal defects within tapped holes. In modern high-precision manufacturing processes—such as the production of engine blocks, transmission housings, automotive chassis frames, aerospace structures, and pressure components—tapping operations carry inherent risks including broken tap bits embedded in holes, missing thread pitches, damaged thread crests, micro-cracks, or improper thread depth. Identifying these flaws prior to final assembly is critical to preventing costly production downtime and structural failures.

Engineered for industrial testing environments, the Micro-Fix NT-1 delivers ultra-fast measurement speeds and uncompromised reliability. Utilizing advanced non-destructive testing (NDT) sensor technology, the instrument inspects the internal thread geometry without causing damage to the workpiece. Upon probe insertion into the tapped hole, the system immediately evaluates thread pitch uniformity, presence of structural cracks, or residual metal chips, delivering instant visual and audible Pass/Fail evaluation results.

Featuring a compact, ruggedized industrial casing and flexible operational capabilities, the Micro-Fix NT-1 can be utilized as a handheld device for manual QA/QC checks or seamlessly integrated into automated robotic production lines for high-volume manufacturing. Accommodating a wide selection of interchangeable sensor probes, it provides a complete, reliable quality control solution for all tapped hole inspection needs.
