The JBO Thread Ring Gauge (NoGo) — Metric Fine, Right Hand, 6h, M1.6 x 0.2 — is a precision tool designed to verify external thread diameters with reliability. It’s a practical go/no-go gauge for inspectors, machinists, and quality professionals who need fast, accurate checks on small-thread components.

Made from hardened steel for exceptional wear resistance, this gauge stands up to daily use in busy workshops. Its simple, intuitive design helps users quickly identify non-conforming threads, supporting efficient quality control and precise engineering steps.

• Accurate Go/No-Go Verification: Quickly confirm external threads meet the No-Go limit, delivering fast, reliable pass/fail results during inspections.
• Durable Hardened Steel Construction: Built to last in busy shops, resisting wear so accuracy stays intact after repeated use.
• Designed for Metric Fine Threads (M1.6 x 0.2) with Right-Hand 6h: Precisely aligned to the target thread class, ensuring consistent checks with common small-thread parts and standard inspection workflows.

Using this gauge integrates smoothly into your QC workflow to reduce downtime, improve measurement confidence, and deliver consistent, traceable results across batches. It helps your team quickly identify out-of-tolerance components, minimize rework, and support reliable assembly with accurate thread mating.
