The JBO Thread Plug Gauge is a precision Go/No-Go tool designed for metric fine threads. Specifically arranged for right-hand M18 x 0.75 holes with a 6H tolerance, this gauge helps you confirm whether a threaded hole will accept mating components without guesswork.

Built for professional use, it delivers fast, definitive checks that keep production moving and ensure consistent fit across parts. The robust hardened steel construction withstands everyday workshop use, providing reliable performance over many cycles.

• Go/No-Go design for fast acceptance testing: Quickly determine if a hole meets the spec; a simple pass/fail reading reduces inspection time and minimizes rework.
• Durable hardened steel construction: Tough enough for daily use in busy shops, resisting wear to preserve accuracy and extend gauge life.
• Metric fine-thread compatibility: M18 x 0.75, 6H, right-hand: Precisely sized to industry standards, ensuring consistent results when pairing with standard metric components and assemblies.

This gauge streamlines quality control by turning complex thread checks into a simple, repeatable process. You’ll save time on inspection, reduce rejects, and improve overall assembly reliability. Its durable build means fewer replacements and consistent performance across shifts and operators.
