Description
The JBO Thread Plug Gauge is a precision inspection tool tailored for metric coarse threads. Designed for machinists, quality control teams, and maintenance professionals, its Go/No-Go design provides quick, reliable verification of threaded holes to ensure proper fit and function. The compact, hand-friendly gauge is ideal for fast checks in busy workshops, job sites, or a production line.
Built for daily use, the gauge features a knurled, easy-to-grip body with color-coded ends that clearly differentiate the Go and No-Go sides for fast identification. Crafted from hardened steel, it resists wear and maintains accurate sizing even after repeated inspections, helping you sustain consistent results over time.
- Go/No-Go quick checks: The paired GO and NO-GO ends deliver immediate pass/fail feedback, allowing you to approve correct holes or stop at the first sign of a mismatch, saving inspection time and reducing guesswork.
- Durable hardened steel construction: Withstands daily shop use and resists wear, maintaining precise tolerances for long service life and dependable performance.
- Metric coarse-thread calibration (M1.7 x 0.35, Right-Hand, 6H): Specifically tuned for common metric coarse threads, ensuring your checks reflect real-world assemblies and support consistent quality control.
This gauge helps you streamline quality assurance, shorten production cycles, and improve overall assembly reliability. By delivering clear, repeatable results, it supports standardized inspections across teams and projects—from rapid prototyping to full-scale manufacturing—so you can trust your threaded holes to perform as intended every time.
