Description

The JBO Thread Ring Gauge (GO) is a precision inspection tool designed to verify external thread diameters on metric M50 x 1.5 right-hand threads. It’s an essential aid for professionals working with electrical conduit components, fasteners, and other threaded assemblies who need quick, reliable confirmation that parts meet Unified thread standards. Crafted for accuracy and ease of use, this GO gauge helps ensure proper fit and performance across production, QA, and assembly workflows.

  • GO Gauge for M50 x 1.5 Right-Hand Threads: Precisely sized to verify external thread diameter against standard specifications, enabling fast, confident pass/fail decisions during inspection and assembly.
  • Hardened Steel Construction: Built to withstand daily handling in busy workshops, delivering durable performance and long-lasting accuracy over many cycles of use.
  • No-Go Design for Quick Conformity Checks: Integrated no-go concept helps identify non-conforming threads at a glance, reducing rework and protecting fit and function in the final product.

This gauge supports streamlined quality control, helping you save time on inspections while delivering consistent, reliable results. Use it to validate conduit-related components, ensure proper thread engagement, and maintain confidence in sourcing and manufacturing decisions—especially in demanding environments where precise threading is critical.
