The JBO Thread Plug Gauge is a precision inspection tool designed to verify internal threads in holes to exact UNS standards. It's ideal for manufacturers, automotive and aerospace shops, QA laboratories, and machine shops that need fast, reliable checks for thread conformity. With its Go/No-Go design, you get clear pass/fail results that help ensure proper fitment and reduce rework.

This right-hand gauge is sized for 1 x 14 threads and employs a 2B tolerance, delivering repeatable measurements you can trust across parts and suppliers. Built for demanding environments, it supports quick inspections during production, assembly, and incoming quality checks.

• Go/No-Go Quick Validation: Delivers immediate pass/fail indications so operators can identify conforming vs. non-conforming holes in seconds, speeding up inspections and minimizing guesswork.
• UNS Thread Compatibility (1 x 14) with 2B Tolerance: Precisely calibrated to the UNS standard for the specified size, ensuring consistent acceptance criteria across parts, assemblies, and vendors.
• Durable, Ergonomic Design: Rugged construction with a knurled body and dual threaded ends for easy handling, long life, and reliable use in busy shop environments.

By providing quick, accurate thread verification, the JBO Thread Plug Gauge helps you maintain tight tolerances, reduce downtime, and improve overall assembly quality. It supports faster QA cycles, clearer communication between operators and inspectors, and consistent results across production runs.
