The JBO Thread Ring Gauge (NoGo) is a precision tool designed to verify external threads on metric fine-threaded parts. Sized for M26 x 1.5 with a right-hand thread and 4h tolerance, this NoGo gauge helps inspectors quickly determine whether a component is within spec or out of tolerance. Constructed from hardened steel, the gauge resists wear in demanding shop environments, and its straightforward design makes it easy to identify non-conforming components during quality checks, reducing rework and keeping production moving smoothly.

• Precise NoGo verification for M26 x 1.5 fine-threaded external surfaces: enables quick pass/fail decisions on threaded parts and helps prevent mismatched assemblies.
• Durable hardened steel construction: withstands daily use in busy workshops while maintaining measurement accuracy over time.
• Metric fine, right-hand, 4h standard alignment: ensures consistent, standards-compliant measurements that improve repeatability across inspections.

The gauge helps streamline QC workflows by delivering clear go/no-go results for M26 x 1.5 external threads, reducing inspection time and the risk of passing out-of-spec parts. With hardened steel durability and a design aligned to metric fine-thread standards, it improves repeatability across batches, lowers rework, and gives teams confidence in every threaded assembly—from sourcing to final assembly—thanks to dependable, long-lasting performance.
