The JBO Thread Ring Gauge (GO) - Metric Fine, Right Hand, 6g, M30 x 3 is a precision go gauge designed to verify the outside diameter of metric fine threads. It’s a must‑have for machinists, quality inspectors, and assembly teams who need fast, reliable checks to ensure threaded parts meet the M30 x 3 specification.

Made from hardened steel for exceptional durability, this gauge is built to withstand daily wear in busy workshops. Its right‑hand geometry and clearly defined go dimension let you identify compliant parts quickly, supporting consistent quality across production runs.

• Precise Metric Fine GO Gauge (M30 x 3): Quickly verify external thread diameter against the metric fine standard, delivering consistent pass/fail results to support accurate inspection and standards compliance.
• Hardened Steel Construction: Built to endure tough shop environments with excellent wear resistance, ensuring long service life and stable measurements over time.
• Fast, User-Friendly Go/No-Go Checks: Simple to use on the shop floor—just try the part over the gauge to confirm it conforms or identify needs for adjustment, reducing inspection time and bottlenecks.

This gauge streamlines the quality control workflow by providing a reliable, repeatable method to verify thread size, minimizing rework and downtime. With durable construction and clear pass/fail criteria, it supports consistent results across shifts and teams, helping you maintain precise thread compatibility and document traceable measurements for quality records.
