JBO Thread Plug Gauge (GO) – Metric Fine - Right Hand - 6H - M64 x 1.5 is a precision go gauge designed to verify threaded holes meet exact metric specifications. Ideal for engineers, machinists, quality inspectors, and maintenance teams, it delivers a quick, reliable GO check for hole acceptance. The hardened steel body resists wear in busy workshops, and the knurled surface provides a secure, comfortable grip during use.

• Fast, confident hole acceptance: The GO gauge quickly confirms whether a hole meets the M64 x 1.5, 6H standard, reducing inspection time and avoiding guesswork.
• Heavy‑duty, wear‑resistant construction: Hardened steel with a durable finish stands up to daily use, resisting wear, corrosion, and impact in demanding environments.
• Precise metric fine-thread compatibility: Specifically engineered for metric fine threads (M64 x 1.5) with 6H tolerance, ensuring consistent measurements across tools and operators.

Using the GO gauge supports consistent thread quality, speeds up quality control, and improves overall workflow by delivering quick, repeatable results that you can trust in production and inspection routines.
