The JBO Thread Ring Gauge (NoGo) - Metric Fine - Left Hand - 6g - M85 x 1.5 is a precision tool for verifying external thread diameters on components that use left-handed metric fine threads. Designed for metric fine threads, this gauge supports quick, reliable inspections across manufacturing, quality control, and maintenance environments. Its NoGo configuration helps identify parts that exceed the maximum size, enabling fast decisions and consistent results.

Crafted from hardened steel for durability, the gauge resists wear in busy workshops and maintains accuracy over many cycles. The left-hand, metric fine specification and tight manufacturing tolerances ensure stable measurements, while its straightforward design makes it easy to use for technicians, engineers, and buyers alike. The user-friendly design supports clear identification of non-conforming threads during routine QC checks.

• Metric Fine, M85 x 1.5 (6g) Left-Hand compatibility: Precise external-thread verification for left-handed metric fine sizes, ensuring parts meet the NoGo limit.
• NoGo design for rapid non-conformity detection: Quickly confirms when a thread diameter is out of spec, speeding inspections and reducing rework.
• Hardened steel construction for durability: Built to resist wear in busy shop environments, preserving accuracy over many uses.

Using this gauge, quality checks become faster and more reliable. It helps ensure that only parts meeting the specified external thread size proceed to assembly, improving consistency across productions and helping teams meet tight quality targets with confidence.
