The JBO Thread Plug Gauge is a precision tool designed for metric fine threads. It provides Go/No-Go checks for threaded holes, helping machinists, engineers, and quality teams confirm that parts will assemble cleanly and consistently. Made from hardened steel, this right-hand gauge is built to last in busy workshops and maintenance environments.

Designed for metric fine thread applications (M36 x 1, 6H), it delivers quick, reliable verification without complex measurements. Its rugged construction and precise tolerances mean you can rely on this plug gauge for routine inspection and first-pass pass/fail decisions.

• Go/No-Go quick verification: Instantly confirm whether a threaded hole is within tolerance, speeding up setups and reducing guesswork.
• Rugged hardened steel: Withstands frequent use, resists wear, and maintains accuracy over time in demanding shop conditions.
• Metric fine thread accuracy: M36 x 1, 6H, right-hand: Ensures compatibility with standard components and reliable mating, minimizing misfit and rework.

This plug gauge helps you streamline quality checks, shorten setup times, and ensure consistent results across parts. By clearly distinguishing acceptable and out-of-tolerance holes, it supports faster production cycles, fewer reworks, and greater confidence in assemblies that demand precise metric threading.
