The JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 6g - M120 x 3 is a precision inspection tool designed to verify external thread diameters with reliability. Ideal for machinists, quality-control teams, engineers, and shop-floor technicians, this GO ring gauge helps confirm that threaded components meet exact size and pitch requirements, enabling fast, confident pass/fail decisions during assembly or inspection.

Crafted from hardened steel, this gauge delivers exceptional wear resistance and long-lasting performance in demanding environments. Its metric fine pitch and right-hand orientation are tuned for common industrial fasteners, making the measurement process straightforward and repeatable across multiple parts and batches.

• Accurate external-thread verification: Quickly determine conformance to the M120 x 3 metric fine standard, supporting efficient go/no-go checks and reducing rework.
• Hardened steel, wear‑resistant construction: Built to endure daily use in busy workshops, preserving tension and dimensional accuracy over time.
• Metric Fine (M120 x 3), Right-Hand design: Precisely aligned with common right‑hand fasteners, ensuring compatibility with standard components and equipment.

Using this gauge streamlines QC workflows by delivering fast, repeatable checks that improve consistency across parts and batches. Its durable build and precise tolerances give you confidence in measurements, helping you ship components faster and reduce downtime while maintaining high quality standards.
