The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads, helping engineers, machinists, inspectors, and assembly teams verify internal thread quality quickly and confidently. Its Go/No-Go design enables fast, reliable checks of threaded holes so components fit together smoothly and with less guesswork.

Specifically sized for M36 x 2 with a 6H tolerance and a right-hand orientation, this gauge is built to deliver consistent results in real-world workshop conditions. The robust, hardened steel construction ensures durability and long-lasting performance even in demanding production environments.

• Go/No-Go quick checks for M36 x 2, 6H: Instantly determine if the internal threads meet the Go limit and stay within tolerance, reducing trial fittings and speeding up inspections.
• Hardened steel construction: Resists wear and maintains dimensional accuracy over many uses, providing dependable performance day after day.
• Right-hand orientation for standard assemblies: Aligns with common right-handed thread practices, delivering consistent results across parts and operators.

Using this gauge streamlines quality control, lowers downtime, and helps ensure every threaded hole accepts fasteners and mating components with confidence. It supports faster setup, more reliable fit checks, and improved overall workflow in manufacturing, maintenance, and repair tasks.
