The Asimeto Ring Gauge GO Metric Fine 6g (685 Series) is a precision tool designed for machinists, inspectors, and quality-control teams who need reliable, repeatable checks of tiny cylindrical threads. Built for right-handed use with M2 x 0.35 pitch, this GO gauge streamlines go/no-go testing in tight-tolerance environments.

• Series and Gauge Type: 685 Series GO ring gauge for metric, fine-thread verification
• Thread Specification: Metric Fine 6g, M2 x 0.35 pitch, right-hand threading
• Material: Hardened steel for durability and stable measurements
• Design and Handling: Knurled outer edge and precision-ground faces for easy placement and repeatable testing
• Applications: Suits automotive, aerospace, and general engineering QC workflows
• Compatibility: Optimized for standard go/no-go thread checks on small cylindrical parts

Using this GO gauge reduces guesswork during assembly and inspection, helping operators quickly verify whether a component's threads meet the intended size. The robust steel construction stands up to high-volume production, minimizing tool wear and replacement costs while delivering consistent measurements across shifts. Its right-hand M2 x 0.35 specification ensures compatibility with common miniature fasteners found in precision electronics, automotive components, and instrument housings. In practice, technicians experience faster setup, fewer rejects, and a smoother quality-control workflow.
