The JBO Thread Ring Gauge (NoGo) - Metric Fine, Right Hand, 4h, M80 x 1.5 is a precision inspection tool designed to verify the outer thread diameter of fasteners, nuts, and threaded components. It helps ensure parts meet exact diameter limits in manufacturing, mechanical assembly, and maintenance work.

• Accurate NoGo sizing: Quickly confirms whether a thread diameter falls within the maximum NoGo limit, reducing inspection time and the risk of accepting out-of-tolerance parts.
• Durable hardened steel construction: Built to withstand daily workshop use with excellent wear resistance and long service life, maintaining reliable measurements even in demanding environments.
• Easy handling and clear orientation: Knurled outer edge provides a secure grip, while a visible index marker (including a red indicator) helps fast, correct alignment for quick, repeatable readings on M80 x 1.5 right-hand threads.

In daily workflows, this NoGo gauge supports faster, more consistent inspections, fewer quality rejects, and greater confidence that assemblies meet specification. Its rugged construction and straightforward use make it suitable for engineers, machinists, inspectors, and technicians across fabrication shops, maintenance teams, and field service, helping you improve throughput, reduce downtime, and deliver reliable, compliant results.
