The JBO Thread Ring Gauge GO is a precision tool designed for quick external-thread verification. Specifically engineered for electrical conduit fittings, it matches M40 x 1.5 right-hand threads to help technicians and inspectors confirm proper thread engagement during assembly and quality checks.

Its Go/No-Go design provides clear pass/fail results at a glance, while the hardened steel construction and knurled edge stand up to daily use in busy workshops across manufacturing, automotive, and aerospace environments, including 8g thread tolerance applications.

• Go/No-Go quick verification: Enables fast, unambiguous checks of thread acceptance, speeding inspections and reducing rework by clearly indicating conforming versus non-conforming threads.
• Rugged hardened steel construction: Built for durability in demanding settings, delivering long tool life and reliable performance even with frequent use and handling with gloves.
• Exact M40 x 1.5 Right-Hand thread sizing: Precisely matched to the target conduit threads, ensuring accurate verification against standard specifications for reliable fitment and QA consistency.

Using the JBO Thread Ring Gauge GO streamlines your quality workflow: a single, straightforward tool that confirms correct thread size and orientation, minimizes guesswork, and supports consistent results across batches. This translates to faster inspections, lower downtime, and greater confidence that every conduit connection will assemble correctly on the line.
