The JBO Thread Ring Gauge (GO) - Metric Fine is a precision tool for quickly and confidently verifying external threads on fasteners, shafts, and components. Designed for metric fine pitches and right-hand threads, it helps technicians and inspectors confirm that parts meet exact specifications without guesswork.

Sized for M45 x 3 with a 6g tolerance, this GO gauge provides a reliable go/no-go check that supports accurate threading and quality control across metalworking, automotive, and manufacturing settings. Crafted from hardened steel, it resists wear and maintains its precise dimensions through daily workshop use.

• Metric fine GO gauge for M45 x 3 with 6g tolerance: Quickly confirms external thread engagement and compliance with the exact size and pitch, reducing misfits and assembly delays.
• Durable hardened steel construction: Built to withstand daily use, resisting wear and corrosion to maintain measurement accuracy over time.
• Right-hand thread compatibility and easy use: Optimized for common right-hand threads with a simple, intuitive ring design that speeds inspections and delivers repeatable results.

By using this GO gauge for metric fine threads, you can speed up line-side inspections, reduce guesswork during assembly, and improve consistency across batches. The combination of precise sizing, clear Go/No-Go results, and robust construction means reliable performance in busy shops, maintenance departments, and production floors, helping you deliver quality parts with confidence.
