The JBO Thread Ring Gauge (NoGo) – Metric Fine, Right Hand, 4h, M28 x 1.5 – is a precision tool used to verify external thread diameters on fasteners, shafts, and machined components. Designed for engineers, machinists, quality teams, and workshop professionals, it delivers a clear limit check to quickly confirm whether a part meets the exact M28 x 1.5 right-hand thread specification. This NoGo gauge helps prevent mismatches, reduce rework, and support consistent assembly across production and inspection processes.

• Precisely machined NoGo limit for M28 x 1.5: Quick and unambiguous go/no-go checks against the 4h tolerance to verify external threads, reducing guesswork and rework in QA and assembly.
• Hardened steel construction for durability: Built to withstand daily use in busy workshops, resisting wear to maintain accurate measurements over time.
• User-friendly design and orientation: Right-hand threading and intuitive layout make it easy to set up, insert, and read, speeding inspections and minimizing operator errors.

With the JBO Thread Ring Gauge, you gain a reliable, fast method to confirm thread compatibility, streamline quality control, and ensure consistent fits in assemblies. Its durable build and precise NoGo limit reduce downtime, lower scrap rates, and give your team confidence that parts meet exact specifications before moving to production or assembly.
