The Asimeto 686 Series Ring Thread Gauge (NoGo) provides a precise, one-sided check for metric M58 x 2 right-hand threads, ensuring they stay within the stringent 6g tolerance class. Crafted for professionals in manufacturing, quality control, and mechanical assembly, this NoGo gauge helps confirm that fasteners do not exceed the maximum allowable pitch diameter.

• Size and standard: Metric M58 x 2, right-hand thread, 6g tolerance class for accurate pitch diameter checks.
• NoGo designation: Specifically designed to determine if threads are too large or out of tolerance by failing to pass through the gauge.
• Series: Part of the 686 Series, built for precision and dependable long-term performance.
• Construction and quality: Produced with high-quality materials and meticulous machining to ensure consistent measurements and durability.
• Measurement purpose: Used to verify maximum material condition of the thread pitch diameter, supporting safe and reliable fastener connections.
• Visual reference: Features a distinct reference mark on the gauge for quick orientation during inspection.
• Application: Ideal for production floors, tool rooms, and quality assurance labs where consistent thread verification is essential.

Using this gauge, inspectors can quickly determine whether a fastener’s pitch diameter remains within spec. When a fastener cannot pass through the NoGo gauge, it signals an out-of-tolerance condition, preventing underspecified components from entering critical assemblies and reducing rework or failures in the field. The result is higher quality assemblies, improved reliability, and streamlined quality control with a clear, repeatable pass/fail standard.
