The JBO Thread Ring Gauge (NoGo) is a precision tool built to verify external BSW threads. Designed for right-hand, medium-class threads in the 1 3/8 x 6 size, it helps shops and QC labs quickly confirm that threaded components meet the required limits. This gauge supports manufacturers across automotive, aerospace, and general machining by providing a clear, fast assessment of whether a part is within specification.

Manufactured from hardened steel, the gauge delivers durable, repeatable measurements in busy environments. The NoGo design makes non-conforming threads easy to spot, enabling fast decisions in inspection routines and reducing the risk of incorrect fits down the line. It’s a trusted, straightforward tool that supports consistent quality across lots and batches.

• NoGo design for rapid non-conformance checks: The NoGo limit lets operators quickly identify threads that are out of spec, speeding up inspections and reducing rework.
• Hardened steel construction for lasting reliability: Withstood wear from repeated use, maintaining accuracy and long service life in demanding shop or production environments.
• BSW 1 3/8 x 6, right-hand, medium class compatibility: Precisely matches common external threads, enabling consistent cross-checks against components and reducing the need for multiple gauges.

Using the JBO NoGo Thread Ring Gauge helps you streamline quality checks, shorten inspection cycles, and ensure threaded parts fit correctly the first time. Its robust construction supports daily use on busy lines, while the clear NoGo indication minimizes guesswork and speeds return-to-production decisions when parts fail to meet specifications.
