The JBO Thread Plug Gauge is a precision tool designed for checking internal metric fine threads. Specifically engineered for M27 x 1.5, this right-hand plug gauge helps machinists, inspectors, and assembly professionals verify that threaded holes meet exact tolerances before parts go together. Its Go/No-Go design lets you confirm fit quickly and confidently, reducing guesswork and downtime in your workflow.

• Fast, confidence-boosting Go/No-Go checks: Quickly determine if the M27 x 1.5 threads are within tolerance, speeding up inspections and preventing mismatched assemblies.
• Durable hardened steel construction: Built to withstand daily workshop use, resisting wear to deliver repeatable, long-lasting performance.
• Standard metric fine-thread compatibility (M27 x 1.5, 6H, Right-Hand): Aligns with common internal thread specifications, providing reliable, consistent results across parts and projects.

This plug gauge provides a practical, reliable solution for ensuring threaded holes are ready for assembly. By combining quick Go/No-Go verification with rugged construction, it supports accurate part mating, reduces rework, and helps maintain quality across production runs and maintenance tasks.
