The JBO Thread Ring Gauge (NoGo) – Metric Fine is a precision inspection tool designed to confirm external thread diameters on fasteners, fittings, and machined parts. Sized for right-hand M48 x 1.5 threads with a 6h specification, this NoGo gauge helps quality teams quickly verify that a component is within tolerance.

Made from hardened steel for durability, it stands up to regular use in busy workshops and inspection benches. The gauge’s clear sizing and easy-to-handle design support fast, reliable checks, helping you identify non-conforming parts at a glance and keep production moving.

• Durable hardened steel construction: Built from hardened steel for long life and wear resistance, even in demanding inspection environments.
• Precise metric NoGo for M48 x 1.5: Specifically calibrated for right-hand metric fine threads with a 6h tolerance to deliver reliable Go/NoGo checks of external diameters.
• Easy handling and quick identification: Knurled outer edge and clear NoGo marking provide a fast, confident check for nonconforming parts and speed up workflows.

This gauge helps streamline quality control by delivering quick, repeatable checks, reducing rework and scrap, and improving overall workflow efficiency. Its rugged construction means fewer tool replacements and lower maintenance, while its straightforward use supports consistent results across batches and operators. Whether used on assemblies, fasteners, or precision machined components, the JBO NoGo ring gauge provides dependable verification that parts meet specification, every time.
