The JBO Thread Plug Gauge (NoGo) is a precision instrument designed to verify threaded holes to metric coarse, right‑hand specifications. It’s built for quality control and precision engineering, helping ensure that M48 x 5 threads meet the 6H tolerance and fit correctly in a wide range of components and assemblies.

Crafted from hardened steel for durability in demanding shop environments, this NoGo gauge delivers reliable, repeatable inspections. Its user-friendly design—featuring a knurled handle and a clearly defined test end—lets technicians perform quick checks with confidence, reducing guesswork and rework.

• NoGo verification for reliable hole tolerance: Quickly confirms threaded holes are within spec by preventing over-sized holes from passing QC, helping keep parts in-spec and reducing rework.
• Durable, hardened steel construction: Withstands daily use in busy workshops, delivering long service life and consistent, repeatable measurements.
• Exact M48 x 5 Right-Hand, Metric Coarse NoGo target: Provides precise alignment with the intended size and tolerance, enabling fast, confident go/no-go decisions during setup and inspection.

Using the JBO Thread Plug Gauge (NoGo) helps streamline your inspection workflow, shorten downtime, and enhance overall quality by delivering consistent, reliable results. The combination of robust construction and straightforward operation supports efficient validation of threaded components, ensuring every part that passes your QC meets the required standards.
