The JBO Plug Gauge - Metric (STI) is a precision measuring tool designed for metric screw thread inserts (STIs). It is a right-hand gauge sized for M5 x 0.8 with 6H tolerance, built to deliver fast, repeatable checks on every insert.

Manufactured and assessed in accordance with ANSI/ASME thread standards, this plug gauge is DAkkS-calibrated to ensure traceable, auditable measurements. Use it to verify that your metric STI inserts meet spec and to maintain consistent quality across manufacturing, automotive, and aerospace applications.

• DAkkS-calibrated, traceable accuracy: The gauge is calibrated to DAkkS standards, providing traceable measurements you can document for audits and quality records.
• M5 x 0.8 metric STI compatibility, Right Hand: Precisely sized for metric screw thread inserts with a right-hand orientation, enabling straightforward, repeatable checks.
• ANSI/ASME standard-compliant with 6H tolerance: Manufactured to the ANSI/ASME thread system with 6H tolerance, delivering reliable, repeatable results across standard metric inserts.

With the JBO plug gauge, inspectors and technicians can confirm insert specifications quickly, reducing rework and scrap while speeding up QA workflows. The DAkkS-calibrated measurement provides auditable confidence for compliance across manufacturing, automotive, and aerospace programs. The precise M5 x 0.8 sizing and right-hand configuration streamline your inspection process, helping you keep parts within spec and maintain consistent performance in the production line.
