The JBO Thread Plug Gauge (NoGo) - Metric Fine - Left Hand - 6H - M65 x 1.5 is a precision inspection tool designed for metric fine threads. It helps machinists, inspectors, and production teams quickly verify threaded holes meet the M65 x 1.5 size within the 6H tolerance class, ensuring consistent fit and reliable performance.

Crafted from hardened steel with a textured knurled body for a secure grip, this gauge is built to endure busy workshop environments. Its left-hand design supports specialized assemblies, helping you avoid mix-ups when inspecting reverse-threaded components.

• Metric fine M65 x 1.5 NoGo gauge: Precisely calibrated for metric fine threads to quickly indicate holes that exceed the maximum size, enabling fast, reliable pass/fail checks and reducing guesswork.
• Left-hand thread compatibility: Specifically designed to inspect left‑hand threaded components, reducing setup errors and ensuring accurate measurements in specialized applications.
• Rugged hardened steel with knurled grip: Built for heavy use in demanding environments; the durable construction resists wear while the knurled surface provides a secure, comfortable grip for precise handling.

Using this gauge helps streamline quality control, shorten inspection times, and deliver consistent results across batches. It supports reliable verification of 6H hole specifications for metric fine threads, giving you confidence in part quality and fit during production and assembly.
