Optical Inspection & Sorting Machine for Bolts and Screws - Metal Disc
Bolts, screws, ball pins and headed fasteners — dents, cracks, thread damage and 360° surface defects caught at multiple inspection stations.

The machine and the parts it inspects
Photographs from our own catalogue: the machine, sample parts it has inspected and, where shown, the defects its cameras flag.

Screens from the machine's own software: the part as the camera sees it, the measured dimensions overlaid, and the parameter table with master value, tolerance, measured value and the OK / NOT-OK count.
Why manufacturers choose the Metal Disc
Fastener makers choose the Metal Disc for bolts, screws, ball pins and headed fasteners: a dedicated multi-station layout for critical 360° defect inspection and hole-continuity checking.
Questions buyers ask about the Metal Disc
What types of fasteners can the Metal Disc machine inspect?
Bolts, screws, ball pins and headed fasteners — for dimensional inspection, hole inspection and 360° surface-defect inspection.
What dimensions does it check?
Outer diameter, height and angle of the inspected fastener, plus across-flat and across-corner on the head.
What defects does it detect?
Dents, burrs, scratches, cut marks, damage, cracks, thread damage, surface deformities, colour and texture variation — plus OCR/OCV, operation missing, hole detection and absence/presence verification.
Does it inspect the full 360° of a bolt?
Yes. A four-side station covers the outer 360° surface and a top station covers the head 360° surface.
Can it check hole continuity and missing operations?
Yes — hole detection, hole-continuity inspection, operation-missing detection and absence/presence verification are standard checks.
Will it work on your part?
Send 50–100 sample parts to our Bhosari lab and a vision engineer runs them on this machine, free of charge: the checks and the speed confirmed on your own parts before anything is quoted. Or start by describing the part to VisiExpert.
