Asimeto Ring Thread Gauge (NoGo) - Metric - Right Hand - 6g - M18 x 1

The Asimeto Ring Thread Gauge (NoGo) in metric sizing is a precision instrument for verifying the pitch diameter of M18 x 1 right-hand threads. Designed for machinists, quality control technicians, and assembly teams, it provides a clear go/no-go assessment to confirm fasteners stay within the 6g tolerance class.

• Series: 686 Series — crafted for accuracy and long‑lasting performance.
• Thread Type: Metric, right‑hand threads (M18 x 1) for standard fasteners.
• Tolerance Class: 6g — ensures precise pitch diameter checks within tight limits.
• NOGO designation: Used to verify maximum material condition; if a fastener cannot pass, the pitch diameter exceeds the limit.
• Size & Fit: M18 x 1 gauge size that corresponds to common fastener specifications.
• Material & Durability: High‑quality metallic construction designed for repeated use and stable measurements.

Use the NoGo gauge on production lines or in repair shops to prevent undersized or oversized fasteners from entering critical assemblies. The go/no-go check speeds up inspection, reduces rework, and helps maintain safe, reliable connections across equipment and projects. The 686 Series gauge delivers consistent readings through frequent handling and cleaning, supporting accurate quality control over time.
