The JBO Thread Plug Gauge (NoGo) is a precision inspection tool designed to verify metric coarse threaded holes. It is sized for M45 x 4.5, right-hand threads, and uses the 6H tolerance class to ensure correct fit and reliable performance in quality-critical applications. This gauge is ideal for engineers, machinists, QA teams, and assembly personnel who need confident, fast checks during manufacturing and inspection processes.

• Accurate NoGo verification for M45 x 4.5 metric coarse threads: Quick, pass/fail checks that align with the 6H tolerance, helping you confirm holes accept the correct plug size and reject out-of-spec work.
• Hardened steel construction for long service life: Built to withstand demanding shop environments, delivering durable, repeatable measurements over time.
• Ergonomic, user-friendly design for fast inspections: Knurled grip and straightforward handling enable secure use and consistent results across multiple checks.

Using this gauge streamlines threaded-hole inspections, reduces rework, and supports consistent, reliable thread quality across parts and batches. Its combination of precise sizing and rugged construction helps you meet standards with confidence, improving workflow efficiency and overall production performance.
