A breakthrough in high-speed 360° fastener inspection
General Inspection, LLC has announced the launch of the “Gi-307”, a powerful new fastener inspection and sorting platform designed to redefine quality control for manufacturers producing mission-critical screws and bolts.
The new multi-camera platform combines dimensional metrology, surface defect detection, recess inspection, and optional heat-treatment verification in a single high-speed system.
Built for applications where failure is not an option, the “Gi-307” delivers comprehensive 360-degree inspection using a revolutionary combination of sequenced front and back lighting with seven high-speed inspection cameras. Unlike conventional inspection systems that struggle to balance dimensional accuracy with reliable surface defect detection, the “Gi-307” performs both simultaneously – at production speeds up to 300 parts per minute.
The system inspects every critical fastener feature, including threads, diameters, lengths, angles, radii, and straightness, while also detecting challenging visual defects such as cracks, plating failures, corrosion, metal chips, and porosity.
The “Gi-307” also incorporates a dedicated on-axis inspection camera to analyze fastener head recesses, allowing manufacturers to detect defects and dimensional issues in slotted, “Torx”, and “Phillips” drive systems with exceptional precision.
For manufacturers requiring even greater process validation, optional Eddy-Current technology can verify proper heat treatment by identifying improperly hardened parts before they reach assembly or the field.
The result is a next-generation inspection platform capable of replacing multiple standalone inspection processes with a single integrated solution.
“The ‘Gi-307’ was engineered to solve one of the industry’s biggest challenges – achieving true high-speed dimensional inspection and surface defect detection in the same machine without compromise,” said Greg Nygaard, VP at General Inspection, LLC. “Manufacturers today need more than basic sorting systems. They need complete inspection confidence, especially for safety-critical fasteners used in demanding applications.”
The “Gi-307” supports fastener diameters from M2 to M35 and part lengths from 10mm to 150mm, making it suitable for a broad range of automotive, industrial, medical, aerospace, electrical, and heavy-equipment applications.
One of the system’s current deployments involves fasteners used in electrical transformers, where component integrity directly impacts operational safety and long-term equipment reliability. In these environments, defective fasteners can contribute to loosening, overheating, internal short circuits, and catastrophic system failures.
By combining advanced optical inspection, precision metrology, recess verification, and optional metallurgical validation in one high-speed platform, the “Gi-307” gives manufacturers the ability to improve process capability, and protect their reputation in zero-defect production environments.
As quality requirements continue to intensify across global manufacturing, the “Gi-307” positions General Inspection at the forefront of next-generation fastener inspection technology.
