The Asimeto Ring Thread Gauge (NoGo) is a precision tool tailored for engineers, machinists, and quality teams working with metric fasteners. It verifies the pitch diameter of right-hand threads in the 6g tolerance class, helping you confirm fit and reliability on every bolt or screw.

• 6g tolerance class: Precisely engineered to the 6g metric thread standard for consistent pitch-diameter verification.
• NoGo designation: A NoGo ring gauge that determines maximum allowable pitch diameter; if a fastener cannot pass through, it’s out of spec.
• Metric Right-Hand thread: Designed for M42 x 3 right-handed threads, aligned with common industry specifications.
• 686 Series: Part of Asimeto’s precision-focused 686 Series, built for accuracy and long-term reliability.
• Precision-machined steel construction: High-quality material and tight tolerances ensure durable, repeatable measurements in busy workshop environments.
• Knurled outer edge: Textured surface provides a secure grip for quick handling during inspection, even with gloves.

Using the Asimeto NoGo gauge helps you catch out-of-tolerance fasteners before they reach assembly, reducing rework, downtime, and safety risks. It supports rigorous quality control on the shop floor or in the lab, ensuring only correctly sized fasteners contribute to strong, reliable connections. Ideal for production lines, maintenance teams, and machining centers that demand consistent thread diameters and traceable measurement results.
