The Openex Fastener Inspection Machine is a high-speed AI vision inspection system designed for automatic quality control of screws, bolts, nuts, studs, and other precision fasteners.
Using multi-camera optical inspection and deep-learning defect detection, the system can inspect surface defects, dimensional errors, thread damage, and head defects at speeds up to 1200 pieces per minute.
This enables fastener manufacturers to achieve 100% automated inspection, reduce labor costs, and ensure consistent product quality before shipment.
Why Fastener Inspection Is Critical
Fasteners are used in automotive, aerospace, electronics, and machinery, where even a small defect can cause major failures.
Common quality problems include:
- Thread damage
- Head cracks
- Burrs or flash
- Missing threads
- Dimensional deviations
- Surface scratches
- Plating defects
Traditional manual inspection is slow and inconsistent. The Openex AI vision system ensures reliable, repeatable inspection at industrial production speeds.
Key Features of the Openex Fastener Inspection Machine
High-Speed Inspection
- Inspection speed up to 800–1200 pcs/min
- Continuous feeding and automatic sorting
- Suitable for mass fastener production lines
Multi-Camera Vision System
The system can be configured with 6–12 high-resolution cameras to capture: top view, side view, thread profile, head geometry, and surface defects.
Multiple lighting configurations ensure clear detection of even tiny defects.
AI Defect Detection
Traditional machine vision struggles with complex surface defects.
The Openex system integrates deep-learning AI algorithms capable of detecting: irregular scratches, micro cracks, plating defects, and unpredictable surface anomalies.
This greatly improves inspection accuracy for difficult defect types.
Precision Dimensional Measurement
The system can also perform dimensional inspection, including:
- head diameter
- shank diameter
- length measurement
- thread pitch detection
- concentricity inspection
High-resolution cameras allow micron-level measurement accuracy.
Automatic Sorting System
After inspection, parts are automatically sorted into:
- OK products
- defect products
- optional multi-grade sorting
This enables seamless integration into automated packaging or downstream production.
Types of Fasteners the Machine Can Inspect
The system is designed for a wide range of fasteners, including:
- Screws
- Bolts
- Nuts
- Studs
- Self-tapping screws
- Machine screws
- Special automotive fasteners
- Custom precision fasteners
Typical part sizes range from M2 to M16, depending on machine configuration.
Detectable Defects
The Openex fastener inspection system can detect a wide range of defects, including:
- Surface Defects: Scratches, Cracks, Burrs, Surface dents, Rust or plating defects
- Structural Defects: Broken head, Missing head slot, Head deformation, Thread damage, Missing thread
- Dimensional Errors: Incorrect length, Diameter deviation, Thread pitch variation, Head diameter deviation
This ensures only fully compliant fasteners reach customers.
