The JBO Thread Plug Gauge is a precision inspection tool designed to verify metric fine threads inside holes and casings. Specifically sized for M24 x 1.5 right-hand threads (6G), it helps manufacturers, machinists, and quality teams confirm proper fit during assembly and inspection.

• Go/No-Go Quick Verification: Quickly determines whether the internal M24 x 1.5 threads are within tolerance, reducing guesswork and rework in assembly and QA.
• Hardened Steel Construction: Built for durability in busy workshop environments; resists wear and maintains accuracy through thousands of uses.
• Two-Ended Go/No-Go Design: One end tests the Go condition and the other tests the No-Go condition, enabling fast, confident pass/fail decisions without swapping gauges.

Designed to streamline threaded-hole inspections, this gauge helps you maintain tight tolerances, reduce downtime, and speed up setup across production lines. The combination of Go/No-Go functionality and robust, wear-resistant steel delivers repeatable, reliable results for M24 x 1.5 internal threads, making it a dependable addition to any quality control or machining toolkit.
