The JBO Thread Ring Gauge (NoGo) – Metric Coarse – Right Hand – 6h – M4 x 0.7 is a precision inspection tool designed to verify external thread diameters on fasteners and threaded components. Ideal for quality control in manufacturing, maintenance shops, and assembly lines, it helps you quickly determine whether a thread falls within the specified tolerance, supporting consistent, reliable measurements across jobs.

Crafted from hardened steel for lasting durability, this NoGo gauge is built to endure daily use in demanding environments. Its right-hand configuration and the 6h metric coarse specification ensure compatibility with common thread forms like M4 x 0.7, delivering dependable performance over time.

• Precise NoGo verification for metric coarse threads: Quickly confirm external thread sizes against the 6h tolerance for M4 x 0.7, helping you spot out-of-spec parts before they move to assembly.
• Durable hardened steel construction: Designed to withstand daily workshop use, resisting wear and maintaining accuracy for long-term reliability.
• Easy-to-use inspection tool for fast non-conforming part identification: Intuitive checks let operators identify rejects quickly, reducing downtime and rework in quality control processes.

Using the gauge simplifies your workflow by delivering fast, repeatable results that support correct fits and dependable performance in every threaded connection. It’s a trusted addition to any QC toolkit, giving you confidence in your measurements and your final assemblies.
