The JBO Thread Plug Gauge is a purpose-built tool for metric coarse threads, specifically designed to verify threaded holes quickly and accurately. Perfect for machinists, inspectors, and assembly teams handling M6 x 1 fasteners, it provides a reliable Go/No-Go check to ensure hole size and pitch meet standard requirements for left-hand threaded components.

• Go/No-Go quick verification: enables fast, confidence-boosting checks of hole readiness, reducing guesswork and rework in daily inspection and assembly tasks.
• Hardened steel construction: engineered for durability to withstand repeated use in demanding environments, delivering long-lasting accuracy and performance.
• Left-hand metric coarse compatibility (M6 x 1, 6H): precisely matched to metric coarse threads and left-hand configurations to ensure reliable fits for the intended fasteners and applications.

Using the JBO Thread Plug Gauge helps streamline your workflow by confirming proper thread engagement before assembly, improving consistency across parts, and lowering downtime due to incorrect threading. Its robust construction and specific thread compatibility give you a dependable, long-term tool you can trust in busy shops and production settings.
