The Asimeto Ring Thread Gauge (NoGo) is a precision tool for engineers, machinists, and quality-control professionals who need reliable verification of metric thread sizes. Designed for right-hand M56 x 1 threads and the 6g tolerance class, this gauge helps ensure only correctly sized fasteners are used.

• Size and standard: Metric M56 x 1, Right Hand threads, 6g tolerance class
• NoGo designation: Quickly confirms whether the thread pitch diameter exceeds the maximum allowable limit
• 686 Series: Precision-built ring gauge crafted for accurate, repeatable measurements
• Gripping design: Knurled outer edge provides a secure, slip-resistant grip in busy workshop environments
• Orientation mark: Distinct red indicator for fast, reliable setup and inspection
• Durable construction: Made with high-quality materials and precision machining to endure repeated use

In practice, this NoGo ring gauge helps you verify that a threaded fastener’s pitch diameter stays within specification. If a fastener cannot pass through the gauge, you know the thread is out of tolerance and may be oversized, preventing improper assemblies. This supports safer, more reliable connections across manufacturing, maintenance, and QA workflows, while reducing rework and inspection time.
