The JBO Plug Gauge for UNF (STI) Helicoil inserts is a precision measuring tool designed to verify UNF thread inserts with dependable, repeatable results. Built for use in manufacturing, automotive, and aerospace environments, it helps ensure proper fit and reliable performance by checking the critical pitch diameter of UNF threaded inserts.

• DAkkS-traceable calibration: Provides a documented, traceable reference for every measurement, supporting quality assurance, audits, and supplier compliance.
• UNF (STI) size No. 10 x 32 pitch-diameter verification: Precisely checks the pitch diameter to ensure correct mating and consistent performance of UNF screw-thread inserts.
• Ergonomic, durable right-hand design: Knurled, robust construction offers secure handling and reliable readings in busy work environments, reducing slips and measurement variation.

This gauge simplifies inspection workflows by delivering quick, accurate checks that help prevent mismatches, rework, and downtime. With its DAkkS-calibrated accuracy and size-specific design, you can rely on consistent results across production runs and quality audits, enhancing confidence in every threaded assembly.
