The JBO Thread Ring Gauge (NoGo) is a trapezoidal, right-hand external thread gauge designed for fast, accurate diameter checks in manufacturing, automotive, and aerospace environments. Use it to verify components conform to Unified thread standards and to quickly identify non-conforming threads.

Crafted from hardened steel, this gauge delivers durability for daily shop-floor use. Its NoGo design provides an immediate, obvious signal when a thread is out of tolerance, helping inspectors and operators prevent mismatched assemblies. This model supports trapezoidal threads in 7e class, Tr. 22 x 5, and is oriented for right-hand threads to match common engineering practices.

• No-Go design for quick tolerance checks: The No-Go feature lets inspectors quickly identify out-of-tolerance threads during inspection, reducing guesswork and speeding up quality control.
• Trapezoidal thread compatibility (7e, Right Hand, Tr. 22 x 5): Precisely sized to match the trapezoidal thread form used in many components, ensuring reliable external diameter checks that align with unified standards.
• Hardened steel construction for durability: Built to withstand daily use in production environments, resisting wear and maintaining accuracy over many cycles.

By choosing the JBO Thread Ring Gauge (NoGo), you gain a reliable, straightforward tool that streamlines inspection workflows. It helps you quickly verify thread fit, catch non-conforming parts before they enter the assembly line, and reduce rework and downtime. The durable construction ensures consistent performance across shifts and teams, giving you confidence in every measurement and every lot.
