The JBO Thread Ring Gauge (NoGo) is a precision inspection tool for checking external metric threads. Specifically designed for right-hand, fine-thread forms at M34 x 0.75 with a 6g tolerance, it helps shops and quality teams quickly confirm parts meet the exact size and fit requirements.

• Precise metric fine threading (M34 x 0.75, 6g): Tailored to the exact thread form, this NoGo gauge provides repeatable, accurate checks that help prevent misfits in assemblies and keep production on schedule.
• Durable hardened steel construction: Built to endure daily workshop use, with wear-resistant surfaces that maintain dimensional accuracy over time and through tough environments.
• Fast, user-friendly Go/No-Go checks: Clear, quick-to-interpret results let inspectors identify non-conforming parts in seconds, reducing rework and speeding up QC workflows.

The JBO Thread Ring Gauge helps you streamline quality control by delivering reliable, repeatable measurements without guesswork. Its rugged construction and precise sizing mean fewer reworks, faster pass/fail decisions, and consistent thread fit across batches—giving you confident inspections and smoother downstream assembly.
