The Asimeto 684 Series Ring Thread Gauge (NoGo) is a precise metric gauge designed for quick, reliable inspection of coarse metric threads. Built for right-handed M5 x 0.8 threads, it helps quality teams verify parts stay within the lower limit of the allowable size.

• Thread Compatibility: Metric coarse 6g threading with an M5 x 0.8 pitch, tailored for tight tolerances in small fasteners.
• NoGo Function: Checks the minimum material condition, ensuring the part remains within the lower size limit and does not undersize.
• Right-Hand Orientation: Specifically configured for right-hand threaded components, aligning with common fastener standards.
• Calibrated Precision: Engineered to verify that the thread diameter stays within the designated tolerance band for consistent results.
• Ring Gauge Design: Compact, hand-friendly circular form with a knurled edge for secure handling during inspection, plus a visible datum marker for quick orientation.

This gauge accelerates the quality workflow by providing a straightforward pass/fail check on threaded parts that must not exceed the maximum size, while also ensuring minimum material requirements are met. Ideal for in-process checks on manufacturing lines, incoming inspection, and machine shop QC workflows, it helps you confidently confirm part conformity without guesswork. Use it on components requiring precise thread size control to reduce rework and waste, and to support consistent assembly performance across batches.
