The JBO Thread Ring Gauge (GO) – Metric Fine, Right Hand, 4h, M15 x 1 is a precision tool built to verify external thread diameters on fasteners, fittings, and machined components. Ideal for engineers, machinists, quality teams, and workshop technicians, it delivers fast, reliable conformance checks against the M15 x 1 standard with repeatable results.

Crafted from hardened steel, this gauge resists wear in demanding environments, ensuring long tool life. The GO design gives a clear pass/fail indication, making inspections quicker and less error-prone. Its right-hand orientation and metric fine specification ensure compatibility with fine-thread parts across automotive, aerospace, and general manufacturing workflows.

• Hardened steel construction: Exceptional wear resistance and long tool life for busy workshops, reducing replacement costs and downtime.
• Precise metric fine GO gauge: Accurate M15 x 1 external thread verification to quickly confirm part conformance and minimize rework.
• Ergonomic knurled grip: Secure handling and easy alignment during checks, speeding up inspections and improving consistency.

With the JBO Thread Ring Gauge (GO) you can streamline thread inspections, reduce guesswork, and maintain consistent quality across production lots. The combination of durable construction, precise dimensions, and straightforward GO checks supports faster throughput, tighter tolerances, and more reliable assemblies in a wide range of industries.
