Description

The JBO Thread Ring Gauge (GO) is a precise external-thread inspection tool designed for electrical conduit fittings. Built for right-hand M75 x 1.5 threads, it helps technicians and inspectors quickly verify fit and function according to standard thread geometry.

Crafted from hardened steel, this gauge delivers durable performance in daily workshop use. Its no-go design supports fast, at-a-glance identification of non-conforming threads, making it easier to uphold Unified thread standards and prevent mismatched components in assemblies.

  • Precision Go Gauge for M75 x 1.5 Right-Hand Threads: Quickly verify that the external thread diameter meets the specified M75 x 1.5 right-hand standard, enabling fast pass/fail decisions during quality checks.
  • No-Go Feature for Clear Conformance: The integrated no-go aspect helps you identify non-conforming threads at a glance, reducing guesswork and preventing faulty fittings from moving forward in production or maintenance.
  • Hardened Steel Construction: Built to withstand daily handling and repeated use in demanding environments, maintaining accurate tolerances and consistent performance over time.

This gauge supports efficient workflow across manufacturing, automotive, and electrical sectors by delivering reliable, repeatable results. Rely on its durable construction and clear pass/fail feedback to improve inspection accuracy, minimize downtime, and ensure your conduit assemblies meet exacting threading standards.
