The JBO Thread Ring Gauge (GO) – Metric Fine, Right Hand, 6h, M17 x 0.5 is a GO gauge designed to quickly and accurately check external thread diameters against metric fine-thread standards. It is ideal for engineers, inspectors, machinists, and quality teams across manufacturing, maintenance, and assembly environments, helping you confirm that threaded components meet the required size and tolerance before use or shipment.

Crafted from hardened steel for lasting durability, this GO gauge stands up to daily use in demanding work settings while preserving accuracy. Its simple, purpose-built design makes it easy to insert and withdraw from threaded parts, enabling fast pass/fail checks and consistent results during routine quality control checks.

• Exact M17 x 0.5 Metric Fine GO Gauge: Quickly verify external thread diameter to the 6h tolerance for right-hand threads, ensuring components meet specification without guesswork.
• Hardened steel construction: Built to withstand daily use in busy workshops, offering wear resistance that preserves accuracy across many inspections.
• Intuitive pass/fail check: Designed for fast, at-a-glance identification of properly conforming threads, speeding up quality control and reducing downtime during setup and assembly.

By using the JBO Thread Ring Gauge, you can streamline external-thread verification, shorten setup times, and improve consistency across production runs. Its durable construction minimizes replacement needs, helping you maintain steady workflows and confident, compliant results in demanding environments.
