The Asimeto NoGo Ring Thread Gauge (684 Series) is a precision tool designed for metric coarse 6g threads, tailored for right-hand M39 x 4 applications. Built for machinists and quality teams, it delivers fast, reliable checks to verify the part’s size is within the lower limit of the allowable range.

• Series: 684 Series, calibrated for metric coarse 6g threads to ensure tolerance adherence.
• Thread Type & Orientation: Metric coarse 6g, right-hand thread configuration.
• Nominal Size: M39 x 4 for accurate sizing in common coarse-thread applications.
• NoGo Function: Checks the minimum material condition, ensuring the part stays within the lower limit of the allowable size.
• 用途: Ideal for measuring threaded parts that should not be larger than the maximum allowable size, supporting consistent QC decisions.
• Construction: Robust ring gauge design with durable metal construction and knurled exterior for easy handling.
• Calibration & Tolerance: Precisely calibrated to maintain reliable tolerance verification across multiple checks.

In practice, this gauge accelerates quality control by delivering a clear pass/fail indication for M39 x 4 threads, helping you prevent undersized components from advancing and ensuring assemblies meet design specifications. Its durable build supports high-use environments, while the specific 6g coarse-thread focus addresses common metric threading applications found in manufacturing and maintenance settings.
