The JBO Thread Ring Gauge (GO) is a precision tool designed to quickly verify the external thread diameter on M12 x 1.5 right-hand threads. It’s ideal for electrical conduit fittings and other compatible components, helping you confirm compliance with Unified thread standards with dependable, repeatable results.

With a clear Go/No-Go design, this gauge makes it easy to spot non-conforming threads, reducing guesswork and preventing improper fitment. Crafted from hardened steel, it stands up to daily use in busy workshops while maintaining consistent accuracy over time.

• Go/No-Go design for fast conformance checks: Quickly confirm that a thread meets the M12 x 1.5 right-hand specification and immediately identify undersized or oversized parts, reducing inspection time and rework.
• Precisely sized for M12 x 1.5 right-hand threads (8g): Delivers reliable diameter measurements aligned with standard thread profiles, supporting consistent quality control across components.
• Hardened steel construction with knurled grip: Built for durability and everyday use in demanding environments, with a secure, comfortable grip that improves handling and reduces slip during measurement.

When you need to confirm thread fit quickly and confidently, this GO gauge streamlines your inspection workflow. It helps prevent misfits in assemblies, minimizes downtime, and supports reliable results across production runs and maintenance tasks. Rely on a rugged tool designed to deliver repeatable measurements and long service life.
