JBO Plug Gauge - Metric (STI) Right Hand - 6H - M6 x 1 - Calibrated (DAkkS Calibration) is a precision measurement tool designed to verify metric screw thread inserts (STIs) used in fast, reliable assembly across manufacturing, automotive, and aerospace sectors. Calibrated to DAkkS standards, this gauge delivers traceable accuracy for quality control and audit readiness, helping you confirm inserts meet exact M6 x 1 dimensions and 6H tolerance.

Designed for engineers, inspectors, machinists, and shop-floor professionals, the JBO plug gauge offers a compact, ergonomic solution for everyday validation of STI inserts. The dual-ended construction provides a straightforward, repeatable means to check insert dimensions during incoming inspection, in-process checks, or final assembly, reducing guesswork and rework.

• DAkkS-calibrated traceability: Measures calibrated against authoritative standards, giving you verifiable, audit-ready results and peace of mind in QA processes.
• Metric STI compatibility — M6 x 1: Precisely sized for metric screw thread inserts, enabling accurate checks of standard inserts and consistent fit across parts and assemblies.
• Durable, ergonomic dual-end design: Built for daily shop use with a knurled body and robust ends, providing secure handling and long-term accuracy even in demanding environments.

Using the JBO Plug Gauge helps you validate insert quality quickly, streamline inspection workflows, and ensure reliable performance in critical applications. With its traceable calibration and purpose-built design, you can reduce downtime, minimize variance between parts, and achieve consistent, high-quality results in manufacturing, maintenance, and product development environments.
