The JBO Plug Gauge - Metric (STI) Right Hand, 6H, M8 x 1.25, calibrated with DAkkS traceability, is a precision tool designed to verify metric screw thread inserts (STIs). It’s ideal for manufacturing, automotive, and aerospace QA teams—as well as engineers, buyers, and shop-floor technicians—providing fast, reliable confirmation that an insert meets exact metric STI specifications.

Designed for fast, repeatable checks, the gauge aligns with ANSI/ASME thread-system standards to ensure consistent readings across lots and audits.

• DAkkS-calibrated for traceable accuracy: Official, documented calibration provides measurement trust and supports quality records and regulatory audits.
• Metric STI compatibility with M8 x 1.25, 6H tolerance: Precisely checks insert threads to the standard metric spec, ensuring reliable fit and assembly performance.
• Rugged, user-friendly design: Dual-threaded ends and a knurled body deliver durable, easy handling for quick seating, reading, and long service life in busy environments.

With the JBO Plug Gauge, inspectors and machinists gain fast, deterministic checks that streamline setup and QA cycles. DAkkS calibration adds confidence for audits and documentation, while its compact, durable design fits neatly into any metrology kit. This gauge helps you reduce rework, keep production on schedule, and consistently achieve accurate, repeatable thread inserts across your manufacturing workflow.
