The JBO Thread Ring Gauge (GO) – Metric Fine is a purpose-built tool for validating external metric threads with speed and confidence. Designed for engineers, machinists, quality inspectors, and maintenance teams, it confirms that components meet the M18 x 1 metric fine thread standard with a right-hand orientation and 6e tolerance during inspection and assembly.

Crafted from hardened steel, this GO gauge delivers exceptional durability in busy workshops. Its simple, intuitive design makes it easy to identify properly conforming threaded components at a glance, helping you keep production moving and quality consistent.

• Metric Fine Go Gauge for M18 x 1 (Right-Hand, 6e): Delivers fast go/no-go checks for external threads, confirming conformity to the exact M18 x 1 metric fine standard and 6e tolerance, so inspection is quick and unambiguous.
• Hardened Steel Construction: Built to resist wear and deformation, delivering long tool life and reliable performance in demanding environments.
• User-Friendly Go/No-Go Verification: Simple pass/fail process lets operators quickly identify conforming parts, reducing inspection time and misreads for consistent quality.

Using the JBO GO thread ring gauge improves workflow by delivering consistent, reliable verification of external threads. It helps reduce rework, accelerate assembly, and support accurate sourcing decisions. With its durable construction and precise sizing, you can rely on this gauge for repeatable results across multiple projects and shifts.
