Introducing the JBO Thread Plug Gauge for metric fine threads. This right-hand Go/No-Go plug gauge is specifically designed for M27 x 0.5 threads with a 6H tolerance, helping teams quickly verify hole acceptance and ensure proper assembly. Built from hardened steel, it delivers reliable performance in daily workshop use and resists wear during repeated inspections.

• Go/No-Go design for fast, confident checks: Quickly determine whether a threaded hole falls inside the required tolerance, reducing inspection time and preventing misfits in assemblies.
• Metric fine-thread compatibility: M27 x 0.5, 6H: Precisely checks the target thread size and tolerance so components thread in smoothly and reliably every time.
• Hardened steel construction for durability: Withstand wear and maintain accuracy through many cycles of use in demanding environments.

With this gauge in your toolkit, you’ll streamline quality control, minimize rework, and ensure consistent, repeatable thread engagement across parts and assemblies.
