The JBO Thread Plug Gauge (NoGo) UNS Right Hand 2B 1 3/4 x 12 is a precision inspection tool designed to verify threaded holes against Unified thread standards. Built to match UNS right-hand thread form, this No-Go gauge helps ensure parts and assemblies meet exact threading specifications in industries like manufacturing, automotive, and aerospace. Its purpose is simple: give you a fast, reliable way to confirm holes are within tolerance before they’re used in critical fits.

• No-Go Verification: Quickly identify non-conforming threads so inspectors can flag out-of-tolerance holes in seconds, reducing rework and the risk of incomplete or loose assemblies.
• UNS Right-Hand Thread Compatibility: Precisely sized for UNS right-hand threads (1 3/4 x 12) with 2B tolerance, delivering repeatable, accurate checks that align with standard specifications.
• Ergonomic, Durable Knurled Handle: The knurled grip and robust design provide a secure hold and comfortable use during repeated measurements in busy workshop environments.

Using the JBO No-Go Thread Plug Gauge helps streamline quality control by delivering clear pass/fail results, supporting consistent thread verification across parts and assemblies. It enables faster inspections, minimizes guesswork during fits, and contributes to reliable performance in critical applications.
