The JBO Thread Ring Gauge (NoGo) – Metric Fine – Right Hand – 6g – M130 x 4 is a precision tool designed to validate external thread diameters on metric fasteners and threaded components.

Engineers, machinists, quality teams, and workshop professionals rely on this NoGo gauge to quickly identify non-conforming threads, helping ensure components meet metric fine threading standards with consistent, repeatable results.

• Precise NoGo verification for metric fine threads (M130 x 4, 6g): Quickly confirms whether a thread diameter is within the maximum limit, enabling fast pass/fail decisions during QA and assembly.
• Hardened steel construction for durability: Built to withstand daily use in busy shops, resisting wear and offering long service life even in demanding environments.
• Right-Hand, easy go/no-go inspection: Designed for standard right-hand threads, delivering clear, fast feedback to speed up quality checks and reduce rework.

With its robust construction and precise sizing, the JBO NoGo gauge helps you streamline inspections, minimize downtime from out-of-tolerance parts, and maintain consistent thread quality across batches. It supports reliable assembly, maintenance, and supplier verification, giving teams the confidence to move parts through your process efficiently.
