The JBO Plug Gauge - Metric (STI) Right Hand is a calibrated inspection tool designed to verify metric screw thread inserts (STIs). Manufactured to align with ANSI/ASME thread standards, this Helicoil gauge delivers precise checks for M24 x 3 inserts used across manufacturing, automotive, and aerospace applications.

Designed for inspectors, machinists, quality teams, and shop floor personnel, it helps confirm insert dimensions quickly and reliably, supporting consistent assembly and repair processes. The rugged, knurled body and dual-threaded ends are built for easy handling in busy environments and for straightforward setup with standard STI tooling.

• DAkkS-calibrated for traceable accuracy: Provides ISO-traceable measurement results you can record in QA logs and compliance documentation, giving you confidence in every check.
• Metric M24 x 3 STI-specific sizing: Precisely matches standard M24 x 3 screw thread inserts, ensuring accurate verification of insert fit without guesswork.
• Durable, easy-to-handle dual-threaded design: Knurled body and two threaded ends enable quick, repeatable checks and secure handling in demanding workshop environments.

Using this gauge improves inspection speed and consistency, reduces rework, and strengthens quality control across production lines. It supports efficient workflow, clearer audit trails, and reliable results when validating metric STIs in industries such as manufacturing, automotive, and aerospace.
