The JBO Thread Plug Gauge (GO) is a precision inspection tool for metric threaded holes, specifically metric fine, right-hand gauge size M48 x 1 with 6H tolerance. Designed for engineers, machinists, quality teams, and workshop professionals, it helps quickly verify that holes are properly tapped and ready for assembly.

• Durable hardened steel construction: Built to withstand daily use in busy shops, delivering long-lasting wear resistance and stable performance across demanding environments.
• Precise metric fine GO gauge (M48 x 1, 6H): Delivers accurate hole verification to the exact size and tolerance, supporting consistent fits and reliable quality control.
• Right-hand threading orientation: Aligns with common right-hand threaded holes, making inspection straightforward and reducing setup time.

Using the JBO GO thread plug gauge helps your team verify threaded holes with confidence, speeding up inspection, reducing rework, and ensuring components meet spec before assembly. Its durable build, precise size, and simple usability support improved workflow, fewer interruptions, and consistent results across machining, fabrication, and assembly tasks.
