Asimeto Ring Thread Gauge (NoGo) - Metric - Right Hand - 6g - M39 x 2

The Asimeto Ring Thread Gauge (NoGo) is a precision metric gauge designed for rapid verification of 6g thread tolerances on M39 x 2 fasteners. Built for machinists, quality inspectors, and precision manufacturers, it delivers dependable pass/fail checks to keep assemblies safe and reliable.

• 6g tolerance class: Specifically crafted to verify the pitch diameter within the 6g metric standard, ensuring consistent threading accuracy.
• NoGo designation: Used to determine if threads are too large or out of tolerance; if a fastener cannot pass through, the thread pitch diameter exceeds the maximum limit.
• Metric right-hand thread: Sized for M39 x 2 with a right-hand orientation, aligning with common metric fastener specifications.
• 686 Series construction: Precision-engineered, built from high-quality materials to deliver durable and stable measurements over time.
• Knurled grip edge: Knurled outer edge provides secure handling and easy manipulation during setup and testing.
• Exact size designation: M39 x 2 nominal size ensures compatibility with corresponding fasteners and gauges in your inspection toolkit.

In practical use, this NoGo gauge is an essential part of the thread inspection process. Pair it with a GO gauge to complete a full Go/NoGo check, confirming that the thread pitch diameter stays within spec and that fasteners will thread smoothly without risk of over-tolerance interference. Ideal for production QC, maintenance, and assembly workflows, it helps reduce rejected parts, prevents misfits in critical joints, and supports consistent, repeatable results across batches.
