Meet the JBO Thread Ring Gauge (NoGo) in Metric Fine — a precise, right-hand gauge designed to verify external thread diameters with confidence. Sized for M105 x 4 and a 6g tolerance class, it’s ideal for inspectors, machinists, and technicians who need fast, repeatable checks on fasteners, fittings, and threaded components.

• Accurate NoGo verification for metric fine threads: Quickly confirms whether external threads meet the target size (M105 x 4) so you can pass, flag, or rework parts without guesswork.
• Rugged hardened steel construction: Built to withstand daily wear in busy shops and production lines while preserving dimensional accuracy and long tool life.
• Right-hand orientation for easy integration: Specifically designed for standard right-hand thread inspection setups, delivering consistent results with minimal setup.

This gauge simplifies quality control by providing a clear, objective pass/fail indication for external threads, helping you reduce downtime, minimize scrap, and maintain precision across assemblies. Its durable build and straightforward use make it a dependable choice for engineers, machinists, and quality teams seeking reliable, repeatable measurements.
