Rotating Bolthole Scanners

Rotating bolthole scanners provide fast, reliable eddy current inspection of fastener holes for fatigue cracks. Their motorized rotating probe design ensures 100% circumferential coverage with consistent lift-off and minimal operator influence.

Bolthole fatigue cracks are among the most critical defects in aerospace and structural components. Evident's rotating bolthole scanners use motorized rotating probes to achieve complete circumferential coverage of fastener holes, detecting cracks as small as 0.5 mm. The integrated encoder provides precise position data for reliable sizing and reporting. Compatible with standard eddy current instruments and available in multiple diameter ranges, these scanners streamline inspection processes while delivering the repeatability required by aerospace standards.
