The JBO Thread Plug Gauge (GO) is a precision inspection tool designed to quickly verify metric fine-threaded holes for the Go limit. Sized M80 x 1 with a 6H internal tolerance and right-hand threading, it helps machinists, inspectors, and assembly teams confirm that holes will accept standard fasteners without guesswork.

• Precise metric fine GO gauge (M80 x 1): Delivers a reliable go-limit check for metric fine threads, giving fast, unambiguous pass/fail results during quality checks.
• Durable hardened steel construction: Built to withstand daily shop wear with excellent wear resistance, helping maintain accuracy over many inspection cycles.
• Ergonomic knurled grip for easy handling: The textured body and right-hand design provide a secure, comfortable grip and quick, repeatable hole checks, even with gloves.

In everyday quality control and precision engineering workflows, this GO gauge accelerates threaded-hole inspections, reduces rework, and supports consistent part acceptance. Its robust, wear‑resistant construction minimizes tool replacement and downtime, while the straightforward Go check simplifies training and execution. Use it to validate that M80 x 1, 6H threaded holes meet the required standard, ensuring reliable performance in assemblies and downstream manufacturing processes.
