The Asimeto NoGo Ring Thread Gauge (686 Series) is a precision metric tool designed for machinists, quality control professionals, and fastener manufacturers who need accurate verification of thread pitch diameter on M11 x 1 right-hand threads.

• Series: 686 Series – precision-built ring gauge crafted for reliable, repeatable thread measurements.
• NoGo designation: NoGo gauge – quickly indicates if the thread pitch diameter exceeds the maximum allowable limit.
• Thread size: Metric, right-hand thread, M11 x 1.
• Tolerance: 6g tolerance class – tight, standards-aligned pitch diameter specification for external metric threads.
• Construction: Made from high-quality materials with precision-ground surfaces for durability in demanding workshop environments.
• Orientation: Right-hand gauge designed to match common production and inspection workflows.

Using the NoGo ring gauge provides an immediate go/no-go verdict: if a fastener cannot pass through the gauge, its thread pitch diameter is outside the accepted range. This helps prevent undersized or oversized fasteners from entering assemblies, reducing rework, improving reliability, and supporting consistent, safe connections across production and maintenance tasks. Ideal for QC labs, machine shops, and quality-driven fabrication environments, the 686 Series gauge delivers lasting accuracy and straightforward verification in a compact, durable form.
