Asimeto's Ring Thread Gauge (NoGo) in Metric is a precision tool crafted for quality control on metric fasteners. Designed for right-hand threads and the 6g tolerance class, it quickly verifies the pitch diameter of M42 x 2 threads to ensure only correctly sized fasteners are used in assemblies.

• Series: 686 Series ring gauges engineered for durable, repeatable performance.
• Tolerance Class: 6g metric tolerance for accurate pitch-diameter assessment.
• Designation: NOGO gauge capability to determine if threads are too large or out of tolerance.
• Thread Specification: Metric right-hand thread M42 x 2.
• Material & Build: Precision-machined from high-quality materials to withstand regular use and maintain accuracy.
• Handling: Knurled outer edge for secure grip and easy alignment during inspection.

The NOGO designation provides a clear pass/fail result: if a fastener cannot pass through the gauge, its pitch diameter exceeds the maximum allowable limit for the 6g class, signaling a non-conforming part. This helps prevent mismatched components, reduces assembly issues, and supports safer, more reliable connections in manufacturing and maintenance environments. With its robust construction and precise tolerances, this gauge delivers consistent measurements across multiple checks, making it a dependable tool for QA technicians, machinists, and assembly engineers working with M42 x 2 fasteners.
