The JBO Thread Ring Gauge (NoGo) is a precision inspection tool for external metric threads.

Designed for metric fine threads (Right Hand, 6g, M35 x 0.75), it enables quick, reliable checks to verify parts meet specifications.

• NoGo undersized thread verification: Quickly identifies non-conforming components, speeding inspections and reducing rework.
• Hardened steel construction: Delivers long service life with excellent wear resistance, maintaining accuracy in busy workshops.
• Precise metric fine threading spec (M35 x 0.75, Right Hand, 6g): Ensures consistent, standards-aligned measurements across threaded parts.

In daily use, this gauge supports efficient quality control by providing a clear pass/fail indication for external threads. Its robust design helps you maintain reliable results across batches, minimize downtime, and inspire confidence in every threaded component you manufacture or source.
