The JBO Thread Ring Gauge NoGo is a precision tool designed to quickly verify the external thread diameter of metric fine-thread components. Sized for M11 x 1 and specified for left-handed applications (6g), it delivers reliable pass/fail checks that align with standard machining and inspection workflows. This gauge is ideal for engineers, machinists, quality inspectors, and workshops seeking consistent, repeatable results in threaded assemblies.

Crafted for durability and long service life, this gauge uses hardened steel to resist wear in busy environments. Its meticulous construction and precise dimensions support accurate inspections, helping you identify non-conforming parts at a glance and keep production moving smoothly.

• Precise metric fine thread size (M11 x 1) NoGo gauge: enables accurate verification of the maximum allowable external thread diameter, ensuring parts meet exact specifications with quick, decisive go/no-go results.
• Durable hardened steel construction: delivers excellent wear resistance and longevity, reducing replacement costs and downtime in demanding shop environments.
• Left-hand thread optimized design: tailored for left-handed threading applications, providing clear, easy-to-interpret results that integrate seamlessly into standard inspection routines.

Using the JBO NoGo Thread Ring Gauge helps you streamline quality control, minimize rework, and improve consistency across parts and runs. Its combination of precise dimensions, robust build, and purpose-built left-hand configuration gives you confidence in every measurement and smoother, more reliable manufacturing workflows.
