The JBO Thread Plug Gauge is a UNF Go-No/Go plug gauge with right-hand threading and a 2B specification, sized for 7/8 x 14. It’s designed to help professionals across manufacturing, automotive, and aerospace verify threaded holes quickly and accurately, ensuring components meet Unified thread standards with confidence.

• Go-No-Go for fast, reliable acceptance: Quickly determine whether a threaded hole is within spec or requires rework, reducing inspection time and preventing misfits in assemblies.
• UNF 7/8 x 14, right‑hand, 2B specification: Precisely matched to the targeted thread size and standard, delivering consistent, easy-to-interpret results that support high-quality fits and reliable performance.
• Durable, hand‑tool construction: Built to endure daily use with a secure knurled grip and robust metal ends, providing long-lasting accuracy in busy workshops or production lines.

This plug gauge helps streamline your quality checks, minimizes downtime, and supports repeatable results across batches. By enabling clear go/no-go decisions, it improves workflow efficiency and ensures threaded components meet the right standards for fit and function—whether you’re assembling vehicles, aircraft components, or precision machinery.
