The JBO Thread Ring Gauge (GO) – Metric Coarse – Right Hand – 6g – M36 x 4 is a precision inspection tool designed to quickly verify external threads meet the standard coarse thread size. Built for quality control, manufacturing, and precision engineering, this Go gauge helps ensure parts mate correctly with their corresponding fasteners and fittings, reducing guesswork during assembly.

• Go-side precision for fast pass/fail checks: The Go side is exactly dimensioned to the M36 x 4 coarse-thread standard, enabling immediate, confident acceptance or rejection of parts during routine inspections.
• Durable hardened steel construction: Designed for daily use in busy shops and laboratories, it resists wear and maintains calibration over many cycles of insertion and removal.
• Right-hand metric coarse threading (M36 x 4, 6g): Specifically tuned to common coarse-thread components, ensuring reliable, repeatable measurements and easy integration into existing inspection protocols.

Used in quality control, machining, and assembly workflows, this gauge helps streamline inspections, minimizes rework, and supports consistent thread engagement across parts. With its rugged construction and precise Go measurement, you can trust your thread checks to be quick, repeatable, and accurate, every time.
