The JBO Thread Ring Gauge (NoGo) — Metric Fine — Right Hand — 6g — M25 x 0.75 is a precision inspection tool used to verify external thread diameters. Designed for engineers, buyers, machinists, technicians, and hobbyists, it helps you confirm that threaded components meet exact size limits without guesswork.

Its NoGo design delivers quick, decisive checks for parts that are out of tolerance. Crafted from hardened steel, this gauge resists wear to deliver reliable performance in busy workshops and production lines, even with frequent use. It is specifically tuned for metric fine right-hand threads (M25 x 0.75) in the 6g tolerance class, making it a dependable choice for quality control and precision engineering.

• Precise metric NoGo limit for M25 x 0.75 (right-hand, 6g): Quickly confirms whether external threads are within spec, reducing inspection time and rework.
• Hardened steel construction: Delivers long-lasting durability and wear resistance in daily use.
• Clear, easy-to-read go/no-go feedback: Helps operators identify non-conforming parts at a glance, speeding up QC checks.

With these features, the JBO Thread Ring Gauge helps you streamline inspections, improve consistency across parts, and protect downstream performance by ensuring every threaded connection meets its exact specification.
