The JBO Thread Ring Gauge (NoGo) – Metric Fine, Right Hand, 6e, M28 x 1.5 is a precision inspection tool designed to verify external thread diameters. Built for engineers, machinists, quality teams, and maintenance staff, it helps ensure threaded parts meet exact size and pitch requirements with minimal fuss. Crafted from hardened steel, this NoGo gauge delivers durability and wear resistance for everyday use in demanding environments.

The user-friendly ring design enables quick identification of non-conforming threads, supporting efficient quality control and consistent results across batches. Whether for fasteners, fittings, or machined components, this gauge provides reliable, standards-compliant checks every time.

• Efficient No-Go Verification: Quickly confirms undersized or out-of-spec threads, reducing inspection time and downstream rework.
• Hardened Steel Durability: Built to resist wear and maintain precise dimensions through heavy use and challenging shop conditions.
• Metric Fine, 6e, M28 x 1.5 Right-Hand: Ensures exact compatibility with standard metric fine threads and delivers consistent go/no-go results across parts.

Using this gauge helps streamline your workflow, improve measurement confidence, and support traceable quality control. With its rugged construction and exacting specifications, you’ll experience faster checks, fewer threading errors, and clearer, repeatable results that you can trust in daily operations.
