Meet the Asimeto Ring Thread Gauge (NoGo) in metric size—a precision tool for quality control and fastener validation. Designed for right-hand, 6g threads, it helps ensure every M8 x 0.75 connection is safe, reliable, and within spec.

• Series: 686 Series, crafted for precision and durability.
• Thread Size: Metric M8 x 0.75, right-hand thread.
• Tolerance: 6g tolerance class for accurate pitch diameter measurements.
• NOGO Designation: Quick pass/fail indication—if a fastener cannot pass through, the pitch diameter is outside the maximum limit.
• Design & Handling: Knurled rim for secure grip and stable alignment during checks.

The NOGO feature provides immediate quality-control feedback, helping you reject oversize or out-of-tolerance threads before assembly, maintenance, or production runs. This reduces the risk of poor fits, cross-threading, and part rejection, while streamlining inspection workflows. Ideal for machine shops, maintenance teams, and any operation that relies on precise metric thread sizing, the Asimeto 686 Series ring gauge delivers consistent measurements and dependable performance over time.
