The JBO Plug Gauge is a metric (STI) go/no-go gauge designed to verify Screw Thread Inserts (STIs), including STI wire inserts, with M14 x 2 threads. Right-hand, 6H tolerance, and calibrated with DAkkS traceability, it helps ensure inserts meet exact specifications for reliable assembly in manufacturing, automotive, and aerospace environments. Manufactured and assessed to ANSI/ASME thread standards, this gauge delivers precise, repeatable checks you can trust on every lot.

• DAkkS-calibrated, traceable accuracy: This plug gauge provides certified, error-minimized measurements that support compliant QA records and audits, so you can verify inserts with confidence.
• Rugged knurled body for repeatable checks: The textured grip and durable construction offer secure handling in busy workshops, reducing slip and measurement variation for consistent results.
• Metric STI compatibility: M14 x 2, right-hand 6H: Specifically designed for these inserts, it enables direct checks of fit and tolerance, simplifying inspection workflows without guesswork.

This gauge helps streamline quality control and assembly by delivering fast, reliable verification of insert dimensions. Its calibrated accuracy and durable build support steady production, fewer reworks, and auditable results across manufacturing, automotive, and aerospace applications.
