The JBO Thread Plug Gauge (GO) is a precision tool designed to verify metric internal threads. Specifically configured for M52 x 1 with a right-hand orientation, this GO gauge helps engineers, machinists, inspectors, and maintenance technicians quickly confirm that threaded holes accept a mating thread and meet standard thread specifications. Its main advantage is fast, reliable pass/fail checks that streamline quality control and assembly workflows.

Crafted from hardened steel, the gauge resists wear and deformation in busy shop environments, delivering consistent measurements over many uses. Its precise finish and durable construction minimize measurement drift, supporting repeatable inspections across multiple work orders and setups.

• Fast, reliable GO checks: Quickly determine if a hole accepts a mating M52 x 1 thread, enabling immediate pass/fail decisions and reducing inspection time.
• Durable hardened steel construction: Built to endure daily handling and use in demanding workshops, preserving accuracy and longevity.
• Precise metric fine thread with 6H tolerance: Ensures repeatable, accurate checks for hole quality, supporting consistent thread-fit results across parts.

Using the JBO GO gauge helps you speed up quality control, reduce rework, and improve assembly reliability by ensuring threaded holes meet the exact M52 x 1, 6H standard. With its robust construction and straightforward use, you can rely on it to perform year after year, delivering dependable checks that support efficient manufacturing, precise maintenance, and high-quality production outcomes.
