JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 6g - M39 x 1

The JBO Thread Ring Gauge (GO) – Metric Fine, Right Hand, M39 x 1 is a precision inspection tool designed to verify external thread diameters on fasteners, fittings, and machined components. It’s ideal for engineers, inspectors, machinists, and quality teams who need fast, reliable checks to confirm threads conform to exact standards.

Specifically tuned for metric fine threads, including M39 x 1 right-hand configurations, this GO gauge provides a quick pass/fail indication for properly formed external threads. Crafted from hardened steel, it resists wear and maintains accuracy through demanding use in workshops and production environments.

• Precise Metric Fine Thread Verification: It checks external thread diameter against the M39 x 1 standard, enabling quick pass/fail decisions and reducing rework.
• Hardened Steel Construction: Built to last, this gauge resists wear and maintains accuracy even after repeated use in busy workshops and on production lines.
• User-Friendly GO-Style Inspection: The GO design allows for rapid conformance checks, helping you identify properly formed threads at a glance and speeding up QC cycles.

Incorporating the JBO Thread Ring Gauge into your quality workflow gives you faster, more reliable external thread verification, reduces downtime due to mismatches, and helps you achieve consistent, repeatable results across batches. The combination of metric fine accuracy, durable hardened steel construction, and straightforward GO-style checks delivers confidence for every inspection and supports efficient, high-quality manufacturing.
