The JBO Thread Ring Gauge (GO) – Metric Fine is a precision Go gauge designed for right-hand metric threads. Sized for M56 x 1.5 with 6e tolerance, it provides a reliable way to verify external thread diameters on fasteners, fittings, and machined components, helping ensure compliant parts from the first pass.

Manufactured from hardened steel for durability, this ring gauge resists wear in busy workshops and maintains accurate measurements over time. Its straightforward design supports quick, confident use in quality control, whether you’re inspecting new parts, performing routine checks, or validating assemblies in automotive, aerospace, or general machining environments.

• Precise GO verification for M56 x 1.5: Quickly confirm that external threads meet the minimum diameter and pitch requirements, aiding early detection of out-of-tolerance parts and reducing rework.
• Durable hardened steel construction: Built to withstand regular use in demanding settings, preserving accuracy and extending gauge life for reliable performance over years of service.
• User-friendly, quick inspection workflow: Balanced geometry and smooth threading allow fast, clear go checks with minimal setup, improving throughput on busy inspect-and-assemble lines.

With the JBO Thread Ring Gauge (GO) – Metric Fine, you gain repeatable, confidence-inspiring measurements that support consistent quality, faster inspections, and smoother production workflows across a wide range of industries.
