The JBO Thread Plug Gauge (GO) is a metric fine, right‑hand go gauge designed to verify internal threads in tapped holes, delivering fast go/no‑go checks for quality control. Made from hardened steel and sized M48 x 2 with a 6G tolerance, it provides durable, repeatable measurements for demanding workshop environments.

• Precise GO gauge for reliable thread verification: Quickly confirms that the internal thread will engage properly, supporting accurate inspections and reducing guesswork.
• Hardened steel construction for durability: Withstands repeated use and harsh shop conditions, delivering long service life in busy production settings.
• Metric Fine, Right Hand, 6G with M48 x 2: Aligns with standard internal thread specifications to produce consistent go/no-go results across production runs.

Used in quality control, maintenance, and machining workflows, this gauge helps you determine thread accuracy at a glance, speeding inspections and reducing rework. Its robust design and exact sizing give you confidence that threaded holes meet specification, improving throughput and ensuring reliable, repeatable results in every part.
