The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed for verifying external UNS threads on right-hand, 2A class components in manufacturing, automotive, and aerospace environments. Sized for 1 1/8 x 8 threads, it helps you quickly confirm whether a part meets Unified thread standards and specifications. Built for professional use, it supports accurate, repeatable thread checks across your production and quality control processes.

• No-Go Design for Quick Conformance Checks: A clearly defined no-go segment lets inspectors instantly identify out-of-tolerance threads, reducing guesswork and speeding up pass/fail decisions during routine quality checks.
• Hardened Steel Construction for Durability: Crafted from tough, wear-resistant material that holds its shape and accuracy through daily use on busy shop floors, delivering reliable measurements over time.
• Standard-Grade UNS 2A Right-Hand Sizing: Precisely matched to Unified Thread Standards for 1 1/8 x 8 right-hand threads, ensuring consistent verification and easier traceability in QA records.

This gauge supports streamlined threaded-part inspection—from incoming components to finished assemblies—by delivering fast, dependable diameter checks that align with industry standards. Its robust construction and clearly defined measuring features help you reduce rework, cut downtime, and maintain high-quality results across critical applications in manufacturing, automotive, and aerospace sectors.
