The JBO Plug Gauge - Metric (STI) Right Hand - 6H - M2.5 x 0.45, Calibrated (DAkkS Calibration) is a precision gauge designed to verify metric screw thread inserts (STIs). It’s a reliable tool for engineers, buyers, tradespeople, and inspectors who need fast, repeatable checks of threaded inserts in manufacturing, automotive, and aerospace workflows.

Manufactured and assessed in accordance with ANSI standards for the metric STI thread system, this plug gauge provides traceable, accurate measurements. The rugged metal body features a knurled grip for confident handling in busy shops, and the right-hand orientation supports common inspection setups.

• DAkkS-calibrated precision: Provides traceable, certified measurements that support audits and quality systems, reducing uncertainty in part acceptance.
• Metric STI compatibility (M2.5 x 0.45) with right-hand orientation: Specifically designed for metric screw thread inserts; ensures correct sizing and orientation for efficient, repeatable checks.
• Durable, knurled construction with 6H tolerance: Sturdy metal body with a non-slip grip withstands daily shop use, while the 6H tolerance enables consistent measurements across production lots.

Using the JBO Plug Gauge helps you verify insert conformity quickly, reduce rework, and capture traceable results with DAkkS calibration. Its metric STI alignment (M2.5 x 0.45) and 6H tolerance deliver consistent performance across production lots, supporting tighter quality control in automotive, aerospace, and general manufacturing environments. The durable design and simple handling keep inspections moving smoothly, so you can make confident acceptance decisions faster.
