The JBO Thread Plug Gauge (GO) - Metric Fine - Left Hand - 6H - M65 x 2 is a precision go gauge designed to verify threaded holes with M65 x 2 left-hand threads. Built for engineers, machinists, inspectors, and quality teams, it helps confirm that a hole meets the required standard and tolerance without guesswork. Crafted for reliability in busy shops, this gauge supports consistent, repeatable inspections across a range of projects.

• Precise GO gauge for M65 x 2 left-hand threads: accurately determines whether a hole accepts the GO size, ensuring alignment with the M65 x 2 left-hand specification and 6H tolerance to prevent misfits and rework.
• Hardened steel construction for durability: built to resist wear in demanding environments, delivering long-lasting performance and stable measurements over many use cycles.
• User-friendly inspection aid: simple to use and easy to read, enabling quick identification of correctly threaded holes and speeding up quality control checks with fewer errors.

In daily production and QC workflows, this GO plug gauge helps you verify thread quality fast, reduce downtime, and maintain consistent results across parts and assemblies. Its rugged construction and straightforward design provide reliable measurements you can trust, supporting smoother handoffs between machining, assembly, and inspection stages.
