The JBO Thread Ring Gauge (NoGo) - Metric Fine is a precision tool for inspecting external thread diameters on fasteners, fittings, and threaded components. Designed for right-hand metric fine threads, it targets M115 x 3 with a 6g tolerance class and uses the NoGo principle to verify that the maximum size does not exceed specification. This makes it ideal for ensuring parts meet required standards before assembly or shipment.

Ideal for engineers, buyers, tradespeople, hobbyists, and quality teams, this gauge supports quick, reliable inspections that help maintain consistency and reduce rework in production lines, workshops, and service environments.

• Precise NoGo for M115 x 3 Right-Hand Threads: Quickly confirms the external thread diameter stays within the maximum limit for this size, enabling confident go/no-go decisions and consistent part quality.
• Hardened steel construction for durability: Built to resist wear, corrosion, and daily workshop use, preserving accuracy through extensive use and diverse environments.
• User-friendly ring gauge design: Easy to handle with clear geometry, allowing fast alignment and inspection even in tight spaces, supporting efficient quality control workflows.

This gauge helps streamline threading inspections, reduce rework, and ensure reliable, repeatable results across production runs. Its durable construction and precise sizing make it a dependable addition to any workshop, QC lab, or field service toolkit.
