Designed for machinists, quality control professionals, and assembly technicians, the Asimeto Ring Thread Gauge (NoGo) provides a precise, quick check of metric external threads. Specifically sized for right-hand M18 x 1.5 fasteners, it verifies the thread pitch diameter against the 6g tolerance class to ensure proper fit and safe connections.

• Series: 686 Series ring gauges crafted for precision and long-lasting performance.
• Size and standard: Metric M18 x 1.5, right-hand thread, designed to meet 6g tolerance requirements.
• NOGO verification: NoGo designation determines if threads are too large or out of tolerance by blocking passage when out of spec.
• Material and construction: Built with high-quality materials to withstand daily use in workshop environments.
• Grip and usability: Knurled outer edge for secure handling during measurement tasks.
• Visual orientation: Red indicator mark aids quick alignment and consistent measurement checks.

The gauge accelerates quality control by delivering a clear pass/fail signal for the thread pitch diameter, helping you avoid undersized or oversized fasteners in critical assemblies. By ensuring only parts that meet the 6g tolerance pass through, it supports reliable connections in mechanical systems, automotive maintenance, and precision engineering projects. Built for durability, it remains accurate under daily shop conditions, preserving your thread standards over time.
