JBO Thread Plug Gauge (NoGo) - Metric Fine - Right Hand - 6H - M42 x 2 is a precision inspection tool designed to verify internal metric fine threads. Built for machinists, quality inspectors, and maintenance teams, it provides a reliable go/no-go check for threaded holes. Designed as a NoGo plug gauge for metric fine threads, it quickly confirms whether a hole's internal thread is within specification.

• Metric fine thread accuracy (M42 x 2, right hand, 6H): specifically sized to metric fine standard threads, enabling fast, confident verification of hole threads and reducing guesswork during inspection.
• Hardened steel with knurled grip: durable construction that resists wear in demanding environments, while the textured body ensures a secure, comfortable grip for precise handling.
• NoGo plug gauge for reliable checks: straightforward pass/fail assessment that minimizes downtime and helps maintain consistent thread quality across parts and batches.

This gauge supports efficient quality control by delivering quick, repeatable measurements that align with standard thread specifications. Use it to validate hole readiness for assembly, reduce rework, and ensure parts meet the required metric fine thread tolerances with confidence.
