The JBO UNC Thread Plug Gauge is a precision inspection tool designed to verify internal threads quickly and reliably. It’s a practical choice for machinists, quality inspectors, and assembly teams in manufacturing, automotive, and aerospace environments. Equipped with a right-hand UNC configuration, 2B tolerance, and No. 12 x 24 sizing, this gauge provides fast, repeatable go/no-go checks that confirm threaded holes meet Unified thread standards.

• Go/No-Go Quick Checks: Enables fast pass/fail assessment of internal threads, reducing inspection time and removing guesswork on the shop floor.
• UNC Right-Hand, 2B Tolerance: Engineered to precisely match common UNC threads and tolerance class, providing reliable measurements across production runs.
• No. 12 x 24 Size: Calibrated for No. 12 size threads with 24 threads per inch, ensuring compatibility with standard fixtures and production jigs.

This plug gauge helps streamline quality control by delivering quick, repeatable measurements that reduce rework, minimize downtime, and improve overall threading accuracy in every part that passes through your assembly line. Its ergonomic design supports comfortable use during long inspection sessions, while its precise dimensions give you confidence for audits, supplier qualification, and first-pass acceptance.
