JBO Thread Ring Gauge (NoGo) — Metric Fine, Right Hand, 4h, M11 x 1 — is a precision external-thread inspection tool designed to quickly verify thread diameters against strict standards. Built as a NoGo gauge for metric fine threads, it helps teams identify parts that are out of tolerance with a simple pass/fail check. Crafted from hardened steel, this gauge delivers durability in demanding workshops and features a user-friendly design that makes non-conforming components easy to spot.

• NoGo verification for metric fine threads: Quick checks on external thread diameters to ensure components meet minimum outer diameter and tolerance requirements, reducing rework and scrap.
• Durable hardened steel construction: Withstands daily wear in busy shops and maintains accuracy over long service life, lowering replacement costs.
• Ergonomic, spec-aligned design: Right Hand orientation, 4h tolerance, and M11 x 1 specification, plus a knurled edge, enable fast, confident measurements and straightforward setup for repeatable results.

Using the JBO Thread Ring Gauge (NoGo) helps streamline quality control by quickly confirming whether threaded parts meet the required outer diameter, reducing inspection time and rework. The hardened steel construction stands up to daily shop use, keeping calibration stable and replacement costs low. With its clear sizing and ergonomic handling, teams across engineering, machining, and maintenance can trust measurements and maintain consistent workmanship, improving overall workflow and outcomes.
