The JBO Thread Plug Gauge (NoGo) is a precision tool designed to verify internal metric threads with reliability and ease. Specifically sized for metric fine threads, this gauge helps engineers, machinists, quality inspectors, and maintenance teams quickly determine whether threaded holes meet exact size and tolerance before assembly or production.

Built for hard use, the NoGo gauge is a Right Hand, 6H class device sized for M112 x 1.5. It is crafted from hardened steel to resist wear and maintain accurate dimensions in demanding workshop environments. The NoGo design lets you perform fast, confident checks and identify out-of-tolerance holes at a glance, reducing guesswork and rework.

• Metric fine NoGo design: Enables fast, at-a-glance pass/fail verification of internal threads sized M112 x 1.5 within the 6H tolerance, ensuring holes meet specification without slowing production.
• Hardened steel construction with knurled grip: Delivers durable, long-lasting performance in busy workshops and provides a secure non-slip grip for precise handling, even with gloves.
• Right-hand, standard 6H/M112 x 1.5 specification: Ensures consistent, reliable measurements across parts and assemblies, helping you maintain quality and interchangeability in your processes.

Using the JBO Thread Plug Gauge helps streamline threaded-hole inspections, cut down downtime, and support repeatable, accurate results across batches. Its sturdy build and precise dimensions give you confidence to proceed with assemblies, knowing holes meet the required metric fine thread standards.
