Fastener & Rivet Inspection
Automated AI verification of fastener presence, seating depth, and head integrity on flight-critical aerospace assemblies.
What It Is
A single commercial aircraft contains over 3 million fasteners. Each one must be present, correctly seated, undamaged, and the right type. Missing or improperly installed fasteners are among the most common escape defects in aerospace assembly, and among the most dangerous.
Why It's Hard
- •Massive quantity: thousands of fasteners per panel, each requiring individual verification
- •Similar appearances: correct and incorrect fastener types can look nearly identical at a glance
- •Seating depth variations: flush-head fasteners must be within tight tolerance bands that are difficult to judge visually
- •Inspector fatigue: repetitive verification of thousands of identical points leads to attention degradation
How Overview Solves It
Presence/absence detection: AI classification instantly identifies missing fasteners across entire panels, eliminating the fatigue risk of manual scanning.
Type verification: Train the model to distinguish between fastener types, ensuring the correct hardware is installed at each position.
Head damage detection: Segmentation identifies cracked, chipped, or deformed fastener heads that could indicate installation errors.
Frequently Asked Questions
How many fasteners can Overview inspect per minute?
Throughput depends on your camera setup and panel layout. With the OV20i, you can scan full panel sections and classify all fasteners in the field of view simultaneously, typically hundreds per capture.
Can it detect wrong fastener types in the right holes?
Yes. The AI learns the visual signature of each fastener type (head shape, drive style, material finish) and flags mismatches at specific positions.
