The JBO Thread Plug Gauge (GO) is a precision inspection tool designed to quickly verify threaded holes meet metric fine standards. It’s ideal for quality control teams, machinists, and maintenance technicians who need reliable inside-thread checks for components using M70 x 2 threads. This GO gauge helps confirm correct internal thread size and tolerance with efficiency.

• Durable hardened steel construction: Built to withstand daily use in busy workshops, resisting wear and maintaining accuracy over time.
• Fast go/no-go verification: Clearly indicates whether a hole is within tolerance, reducing inspection time and guesswork.
• Precise metric fine thread (M70 x 2, right-hand 6G): Ensures consistent, repeatable checks for common high-precision threaded holes across multiple applications.

The JBO Thread Plug Gauge GO provides a simple, dependable method to verify internal threads during production, maintenance, or assembly. By delivering quick, repeatable results, it helps teams streamline workflows, reduce rework, and improve overall quality. With hardened steel construction and a design focused on ease of use, this gauge offers reliable performance in demanding environments and long-lasting value in any precision machining or assembly operation.
