The JBO Thread Plug Gauge is a precision tool designed to verify metric fine-thread holes and mating parts. It’s ideal for engineers, machinists, quality inspectors, and workshop enthusiasts who need reliable, quick checks of internal threads. This Go/No-Go gauge is tuned for M24 x 0.5 right-hand threads, helping confirm fit quickly and consistently.

Constructed from hardened steel for long life in busy environments, the gauge resists wear and maintains accuracy even with frequent use. A textured, knurled body provides a secure grip during inspection, so you can work confidently in tight spaces and with small components.

• Go/No-Go quick checks: Quickly verify accept/reject for metric fine threads, reducing inspection time and guesswork.
• Hardened steel durability: Built to withstand daily shop use, resisting wear for reliable, long-lasting performance.
• Precise size and orientation: Specifically tuned to M24 x 0.5 right-hand threads with 6H tolerance, ensuring consistent, repeatable results across parts and setups.

Using this gauge speeds up quality checks, minimizes trial fits and rework, and supports consistent production standards. The durable build lowers replacement and maintenance costs, while the Go/No-Go design delivers clear, binary results that simplify reporting and ensure parts fit correctly the first time.
