The JBO Thread Plug Gauge is a precision inspection tool designed for metric coarse threads, specifically tuned for M7 x 1 holes and 4H internal tolerance. It uses a Go/No-Go design to quickly verify threaded holes meet the required spec, helping ensure reliable assembly and consistent performance.

Crafted from hardened steel for durability, this right-hand gauge stands up to daily shop use. Its compact, knurled body provides a secure grip for fast, repeatable go/no-go checks.

• Go/No-Go Verification for Quick Checks: Instantly confirm whether the M7 x 1 thread hole meets the 4H tolerance, speeding up setups and reducing rework.
• Durable Hardened Steel Construction: Built to withstand daily shop use, maintaining accuracy after repeated insertions.
• Right-Hand, Metric Coarse Design: Precisely tuned for coarse-thread holes in metric standards, ensuring reliable, consistent measurements with standard tooling.

Using the JBO Thread Plug Gauge helps you verify hole readiness quickly, reducing guesswork and preventing misfits in assemblies. It speeds up quality checks, lowers potential rework, and supports consistent results across batches when working with M7 x 1, metric-coarse threads. The hardened steel construction and compact, ergonomic design make it a dependable tool for engineers, machinists, and maintenance teams alike.
