Introducing the Asimeto Ring Thread Gauge (NoGo) for metric threads — a precision tool designed for machinists, quality teams, and manufacturers who demand strict control over thread size. It verifies the maximum pitch diameter for 6g class, right-hand M55 x 1 threads, ensuring only properly sized fasteners move forward in the build.

• 6g tolerance class: Designed to meet the 6g specification, ensuring accurate pitch diameter checks for metric threads.
• NoGo designation: Utilizes the NoGo standard to determine if threads are too large or out of tolerance, supporting reliable pass/fail assessments.
• Metric, right-hand threading: Precisely targeted for standard right-hand M55 x 1 fasteners.
• 686 Series construction: Part of a precision line crafted for durability and repeatable measurements in demanding environments.
• Durable materials: Built from high-quality materials to resist wear and maintain accuracy over time.
• Knurled edge for grip: Textured rim aids handling and alignment during inspection, even with greasy or dusty hands.
• Pitch diameter focus: Specifically tuned to gauge the thread pitch diameter, not just outer dimensions, for true sizing verification.
• Compact, reliable NoGo check: Enables quick, non-destructive QC checks that fit neatly into daily manufacturing workflows.

This ring gauge is ideal for machine shops, assembly lines, and quality control labs that require precise and repeatable verification of metric thread sizes. Use it as part of a two-gauge system (with GO gauges) to streamline inspections, reduce returned parts, and promote safe, reliable fastener connections in critical applications.
