The JBO Thread Plug Gauge (GO) in Metric Fine, Left Hand, 6H, M75 x 2 is a precision inspection tool for verifying internal metric threads in threaded holes. Designed for engineering teams, quality control, and workshop technicians, it provides fast, reliable go/no-go checks to confirm hole conformity to the M75 x 2 specification and 6H tolerance.

Constructed for durability and repeatable accuracy, this GO gauge uses hardened steel and precise grinding to maintain its dimension over many measurements. The left-hand configuration expands its versatility, making it suitable for holes with left-hand threads or special threaded features, without needing multiple gauges.

• Precise GO verification for M75 x 2 threads: Quickly confirms correct thread start and engagement, delivering clear pass/fail results to speed up quality control.
• Hardened steel construction for durability: Resists wear and maintains accuracy in busy shop environments, reducing replacement and rework.
• Left-hand design for specialized applications: Ready-to-use for left-handed threads, increasing versatility and reducing the need for extra gauges.

With this GO gauge in your inspection toolkit, you’ll streamline threaded-hole validation, improve workflow consistency, and ensure components meet exacting standards with confidence.
