JBO Thread Plug Gauge (GO) is a precision tool for quickly verifying metric coarse threaded holes. Sized for M52 x 5 with a right-hand thread and 6H tolerance, this GO gauge is ideal for inspectors, machinists, and quality teams aiming to confirm parts meet standard metric coarse thread specifications.

• Fast go/no-go verification: Quickly confirm whether a threaded hole meets the M52 x 5 metric coarse standard, helping you speed up inspections and keep production moving.
• Durable hardened steel construction: Built to resist wear in busy workshop environments, delivering long-lasting performance and consistent results over time.
• Spec-compliant geometry (Right-Hand, 6H): Ensures reliable, repeatable checks that align with standard threading tolerances for consistent results across parts.

Using this GO gauge helps streamline quality control by delivering fast, reliable go/no-go checks, reducing inspection time and rework. It supports consistent threaded-hole validation across batches, improving overall assembly reliability and uptime. The robust hardened-steel design minimizes wear and replacement costs, while the exact M52 x 5, right-hand, 6H specification gives you confidence that parts will thread together as intended.
