The JBO Thread Plug Gauge is a precision Go/No-Go gauge designed for metric fine threads. It quickly verifies threaded holes to ensure they will accept M7 x 0.75 fasteners, making it an essential tool for machinists, quality technicians, engineers, and maintenance teams who require exact fits without guesswork. Built as a right-hand, 6G gauge, it delivers reliable checks in typical workshop environments, helping you keep assemblies moving smoothly.

• Go/No-Go design: Enables fast, reliable verification of internal threads so you can confirm holes are within spec before assembly, reducing rework and downtime.
• Durable hardened steel construction: Withstands daily use in busy shops, delivering consistent performance and long service life even under repetitive inspections.
• Right-hand metric fine-thread compatibility (M7 x 0.75, 6G): Ensures precise, repeatable checks for common metric fine threads, with an ergonomic, knurled body for easy handling during tight-tolerance work.

This gauge helps streamline your workflow by providing immediate, easy-to-interpret results on thread holes, improving accuracy across assemblies and minimizing production delays. Its robust construction and precise Go/No-Go criteria give you confidence in every check, supporting higher first-pass yields and dependable results in both professional shops and demanding maintenance environments.
