JBO Thread Plug Gauge is a precision inspection tool for metric fine threads, designed to verify internal threads in holes sized M13 x 0.5 with a 6H tolerance. The Go/No-Go design lets you quickly confirm whether a threaded hole will accept a mating part, speeding up setups and reducing guesswork. Built for durability, the gauge uses hardened steel to withstand wear in busy workshops and deliver reliable performance over many inspections.

• Go/No-Go quick checks: Perform fast pass/fail inspections of internal threads to confirm that holes meet the M13 x 0.5 6H specification and will fit mating parts without guesswork.
• Hardened steel construction: Engineered for long life with excellent wear resistance, maintaining accuracy even after repeated use in demanding environments.
• Metric fine-thread compatibility (M13 x 0.5, Right Hand, 6H): Precisely matched to your fine-thread holes, delivering consistent, reliable results for quality control and assembly confidence.

This plug gauge helps streamline quality checks, reduce rework, and ensure consistent fit between components. With a robust build and precise Go/No-Go limits, you can trust it to deliver repeatable results across multiple holes, enhancing workflow and confidence in production, inspection, and assembly tasks.
