JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 6g - M18 x 1.25

The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed for metric fine threads. Specifically, it targets M18 x 1.25 right-hand threads, providing a reliable NoGo check to quickly identify components that are out of tolerance and should be rejected or reworked. Built for use in quality control, machining, and assembly environments, this gauge helps your team confirm that external threads meet exact size requirements with confidence.

Crafted from hardened steel for lasting durability, the gauge withstands daily use in busy workshops while maintaining accurate measurements. The ring design delivers a clear, easy-to-read indication when a part fails to meet the specification, enabling fast decisions and smoother inspection workflows.

• Fast NoGo verification for M18 x 1.25: Quickly confirms whether a thread diameter falls within the NoGo limit, delivering instant pass/fail feedback to speed up QA and reduce rework.
• Hardened steel durability: Built to resist wear in demanding environments, preserving accuracy and extending service life through heavy use.
• Right-Hand metric fine with 6g tolerance: Optimized for standard right-hand threads, ensuring consistent, reliable measurements and uniform results across parts and assemblies.

This gauge helps you streamline inspections, reduce downtime, and ensure components conform to required standards. With its robust construction and precise sizing, it supports engineers, buyers, tradespeople, and quality teams in achieving repeatable, reliable results across manufacturing, maintenance, and production environments.
