The JBO Thread Plug Gauge is a precision go/no-go gauge designed to quickly verify internal threads to Unified thread standards. Sized for UNC 5/8 x 11, Right Hand, 2B class, it helps teams in manufacturing, automotive, and aerospace ensure threaded holes are within specification and ready for assembly.
Its two-ended Go/No-Go design provides fast pass/fail checks, allowing inspectors to identify conforming versus non-conforming threads in seconds and keep production moving without guesswork.
- Two-ended Go/No-Go design: Validate both the acceptable (go) and unacceptable (no-go) thread sizes in a single check, delivering rapid decisions and reducing inspection time.
- Standards-aligned UNC 5/8 x 11 RH, 2B sizing: Precisely matches the target internal thread geometry to ensure consistent conformance against Unified thread standards and minimize QA ambiguity.
- Ergonomic, easy-grip construction: Knurled body and balanced ends provide secure handling for repeatable inspections in busy production environments.
This gauge helps you confirm threaded holes quickly, improving workflow and reducing rework. By delivering clear go/no-go results aligned with standard UNC 5/8 x 11 RH 2B threads, it supports consistent quality across parts and industries, empowering your team to assemble with confidence and accuracy.
