The JBO Thread Plug Gauge is a precision go-no/go tool crafted to reliably verify internal threads in metric sizes, specifically M25 x 1.5 with a right-hand thread. Designed for electrical conduit applications and other threaded holes, it helps inspectors and technicians quickly confirm whether a hole will properly accept a mating thread, ensuring proper fitment and function.

• Go/No-Go Quick Pass-Fail Checks: Instantly identify conforming versus non-conforming threads, speeding up inspection and reducing guesswork during assembly and maintenance.
• 7H Toleranced Internal Thread Check: Precisely sized to verify threads against the 7H class, delivering repeatable, reliable results across parts and operators.
• Rugged, Easy-Grip Design with Visual Cues: Knurled central body plus color-coded end features provide secure handling and quick orientation for inspections in busy workshop environments.

In practice, this gauge helps you streamline quality control, minimize rework, and ensure threaded joints seat correctly on the first attempt. Its straightforward go/no-go method reduces downtime and provides consistent, trustworthy results across shifts and teams.
