The JBO Thread Plug Gauge is a precision Go/No-Go gauge designed for metric fine threads, specifically M32 x 0.5, right-hand orientation, and a 6H tolerance. It’s ideal for engineers, machinists, quality teams, and assembly operators who need fast, confident checks of threaded holes to ensure parts fit together as intended.
Crafted from hardened steel, this gauge resists wear and maintains accuracy even with frequent use in busy workshop environments.

• Go/No-Go quick checks: Enables fast, decisive verification of threaded holes, reducing inspection time and preventing misfits in assembly.
• Metric fine thread compatibility: Precisely tuned for M32 x 0.5 fine threads with 6H tolerance to ensure accurate hole acceptance and consistent mating parts.
• Durable hardened steel construction: Built to withstand heavy use, delivering long service life and stable measurements across production runs.

This gauge helps you streamline quality control, cut downtime, and ensure reliable performance across assemblies. By providing clear pass/fail indications, it supports consistent results, fewer reworks, and smoother workflows from inspection through final assembly.
