JBO Thread Plug Gauge (GO) - Metric Fine - Right Hand - 6H - M80 x 1.5 is a precision go gauge designed to inspect internal metric threads in holes. Built for engineers, machinists, inspectors, and quality teams, it helps quickly confirm that a threaded hole matches the 6H standard and is ready for reliable assembly.

• Hardened steel construction for long-lasting accuracy: The gauge is built from hardened steel to resist wear and maintain precise dimensions through frequent use, even in demanding workshop environments.
• Precise M80 x 1.5 metric fine thread: Ensures you are checking the correct thread size and pitch for large-diameter holes, delivering consistent, repeatable results.
• Intuitive GO-only design for fast inspections: A straightforward go gauge that lets you confirm hole readiness in moments, reducing inspection time and avoiding guesswork.

With this GO gauge in your toolkit, inspections become quicker, more reliable, and less error-prone. The durable construction stands up to daily handling in busy shops, while the exact M80 x 1.5 fine thread aligns with common engineering standards, helping you lock in quality early in the manufacturing process and minimize rework.
