The JBO Thread Plug Gauge is a precision Go/No-Go tool designed for metric fine threads. Specifically configured for M16 x 0.5 holes, this right-hand gauge helps machinists, engineers, and quality inspectors quickly verify that threaded holes meet exact tolerances before assembly. Its Go/No-Go design provides fast, clear pass/fail feedback, reducing guesswork and rework in critical fits.

Built for daily use in workshop and production environments, the gauge is crafted from hardened steel for long life and wear resistance, maintaining accuracy through repeated insertions and removals.

• Go/No-Go design for fast, confident hole checks: Quickly confirm whether a threaded hole meets specification, delivering immediate feedback that speeds setup and reduces downtime.
• Metric fine thread readiness (M16 x 0.5, 6H): Precisely sized for fine-thread holes with 6H tolerance, ensuring only parts that truly fit advance in your process.
• Hardened steel construction for durability: Built to withstand daily use in busy shops, resisting wear and preserving measurement accuracy over time.

Using the JBO Thread Plug Gauge streamlines quality control and assembly workflows. It provides reliable pass/fail signals, helping you reduce rework, shorten inspection time, and maintain consistent results across parts and batches. With durable materials and precise sizing, you can depend on this gauge for repeatable, accurate checks in both setup and in-process scenarios.
