The Asimeto Ring Thread Gauge (NoGo) is a metric, right-hand NoGo ring gauge designed for precision verification of the thread pitch diameter on M45 x 1 fasteners. Part of the 686 Series, this gauge helps inspectors and machinists quickly confirm that threads are within the 6g tolerance class, ensuring reliable fits and safe assemblies.

• Size and tolerance: Metric 6g tolerance class for accurate pitch-diameter checks on M45 x 1 right-hand threads.
• NoGo designation: Specifically designed to indicate when the thread pitch diameter is out of tolerance by preventing passage of over-size fasteners through the gauge.
• Thread specification: Right-hand threads, M45 x 1, for common industrial fasteners.
• Series and craftsmanship: 686 Series ring gauges built for precision and long-lasting performance.
• Material and durability: Manufactured with high-quality materials to endure routine testing in demanding workshop environments.

This NoGo ring gauge provides a decisive, repeatable test that helps reduce guesswork during quality control. By confirming that external threads stay within the maximum pitch-diameter limit, you prevent mismatched fasteners from entering critical assemblies, cut down on rework, and promote consistent torque and seating in production lines. Ideal for maintenance shops, manufacturing facilities, and inspection labs that rely on accurate thread verification for M45 x 1 fasteners.
