The Asimeto Ring Thread Gauge (NoGo) is a precision inspection tool designed for metric coarse threads. Calibrated for 6g M8 x 1.25 right-hand threads, it helps quality teams verify the minimum material condition of threaded parts.

• Series and Threading: 684 Series designed for metric coarse 6g threads, specifically M8 x 1.25.
• Handedness: Right-hand configuration aligns with common fastener threading standards.
• NoGo Function: Checks the minimum material condition to ensure parts stay within the lower size limit.
• Calibration and Tolerance: Precisely calibrated to confirm the thread is within tolerance for reliable fits.
• Construction and Handling: Solid metal body with knurled outer edge for secure grip and consistent handling.
• Visual Datum: Subtle red marker aids quick orientation during inspection without altering measurement outcomes.

With the NoGo gauge, inspectors can rapidly determine if a threaded part is too large to be acceptable, helping prevent undersized components from entering assemblies. This fosters consistent thread performance, reduces rework, and supports reliable fastening in production environments—from manufacturing floors to metrology labs. Ideal for automotive, industrial machinery, and precision manufacturing teams that require dependable, repeatable thread checks for M8 x 1.25 fittings.
