The JBO Thread Plug Gauge is a precision tool designed for metric fine threads, specifically M13 x 0.75, with right-hand orientation and 6G class. It provides a reliable go/no-go check for threaded holes, helping ensure components thread together correctly and consistently in production, repair, and assembly settings.

• Go/No-Go inspection design: Allows fast pass/fail checks—try the go gauge to confirm a hole accepts the thread, then the no-go gauge to confirm it does not—reducing inspection time and human error.
• Metric fine-thread accuracy (M13 x 0.75) with right-hand orientation: Precisely sized for M13 x 0.75 threads and right-hand threads, ensuring reliable measurements that match your production standards.
• Hardened steel construction: Built to endure daily workshop use, resisting wear and maintaining measurement stability over time for consistent results.

With the JBO Thread Plug Gauge, you gain fast, confident verification of threaded holes, helping you reduce rework and assembly delays. Its durable build stands up to busy shop floors, while its precise M13 x 0.75 fit checks ensure components thread cleanly and consistently—whether you're prototyping, manufacturing, or performing routine maintenance. This gauge supports smoother workflows, faster QC decisions, and dependable results across demanding applications.
