The Asimeto 684 Series NoGo Ring Thread Gauge is built for precise verification of metric coarse 6g threads. It’s tailored for inspectors and machinists working with M6 x 1 right-hand threads, ensuring parts stay within the lower end of the size tolerance.

• Series and purpose: 684 Series NoGo gauge calibrated for metric coarse 6g threads to verify tolerance.
• Thread specification: Right-Hand M6 x 1 thread profiling for accurate size assessment.
• Calibration and tolerance: Precisely calibrated to ensure the thread remains within the lower limit of the allowable size.
• Minimum material condition check: NoGo function confirms the part’s minimum material condition aligns with spec, helping prevent undersized parts from passing inspection.
• Ergonomic design: Knurled outer edge for secure handling during checks and a visible datum mark for quick orientation.

In practice, this gauge speeds up quality-control workflows by delivering quick, reliable pass/fail indications for threaded components such as fasteners, inserts, and machined studs. By verifying that threads do not exceed the maximum allowable size and meet the lower limit, you reduce the risk of improper fits, damaged assemblies, and costly rework. Use the NoGo gauge as part of a broader inspection routine to maintain consistent thread quality across production runs and assemblies.
