Take the guesswork out of thread inspection with the JBO Thread Ring Gauge (NoGo) — Metric Fine. Designed for M23 x 0.75 right-hand threads and 6g tolerance, this gauge provides fast, reliable pass/fail checks during production, assembly, and quality control.

Built from hardened steel for long life in demanding shop environments, its straightforward design helps engineers, buyers, tradespeople, and hobbyists quickly spot non-conforming parts and keep workflows moving smoothly.

• Hardened steel construction: Built to withstand daily wear, delivering long-lasting accuracy and durability in busy inspection environments.
• Fast, unambiguous NoGo checks: Clearly shows conforming vs non-conforming threads, speeding up quality control and reducing inspection time.
• Metric fine threading for M23 x 0.75 (right-hand) with 6g tolerance: Ensures the gauge matches your target thread spec for reliable, repeatable measurements across parts and batches.

This gauge helps streamline your inspection process, minimize rework, and ensure consistent results across production runs. With its robust build and precise sizing, you can trust measurements, reduce downtime, and demonstrate reliable quality to suppliers and customers alike—whether you’re in a high-volume manufacturing environment or a precision-focused workshop.
