The JBO Thread Ring Gauge (NoGo) is a precision tool for inspecting external metric threads. Sized for M11 x 0.75, fine-pitch, right-hand threads, it helps engineers, machinists, and inspectors quickly verify thread conformity during production, assembly, and quality checks.

Manufactured from hardened steel, this gauge resists wear and maintains accuracy even in busy workshops. The NoGo design provides a straightforward pass/fail check, enabling fast decisions that keep your workflow moving and your parts within specification.

• Fast NoGo conformance check: Quickly determines whether an external thread diameter exceeds the maximum limit, speeding inspections and reducing guesswork.
• Hardened steel durability: Built to resist wear in demanding environments, ensuring long-lasting accuracy and reliability.
• Metric fine, M11 x 0.75 right-hand compatibility (6e): Precisely matched to common metric fine threads, delivering consistent, reliable checks for M11 x 0.75 components.

Using this NoGo ring gauge streamlines quality control, minimizes rework, and supports repeatable results across batches. Its rugged construction and clear conformance indication help maintain production efficiency, whether in manufacturing, maintenance, or inspection roles.
