The JBO Thread Ring Gauge (NoGo) – Metric Fine, Right Hand, 6g, M145 x 1.5 is a precision inspection tool designed to verify external thread diameters on fasteners, fittings, and machined components. Built for engineers, buyers, maintenance teams, and shop floor technicians, it delivers quick, reliable Go/NoGo checks that help you confirm parts meet exact specifications.

Crafted from hardened steel for exceptional wear resistance, this gauge is built to withstand daily use in demanding environments. Its NoGo design provides a clear, unambiguous indication of non-conforming threads, while the knurled outer edge offers a secure grip for fast setup and measurement in busy workspaces.

• Durable hardened steel construction: designed to resist wear and maintain dimensional accuracy over many cycles, reducing replacement costs and downtime.
• NoGo metric fine threading: enables fast, reliable checks of external threads, speeding quality control and preventing subtle threading rejects.
• Right-hand orientation with M145 x 1.5, 6g specification: ensures compatibility with common components and fixtures, simplifying stocking and delivering consistent results across inspections.

Used within the quality control workflow, this gauge helps you identify non-conforming threads at a glance, accelerating inspections, improving part conformity, and supporting reliable, right‑first‑time assemblies across production runs.
