The JBO Thread Ring Gauge (GO) - Metric Fine is a precision tool for quickly and reliably checking external thread diameters. Designed for right-hand, metric fine threads, it helps inspectors, machinists, and quality teams verify that components meet exact specifications, including M16 x 0.5.

Crafted from hardened steel, this GO gauge delivers outstanding wear resistance and long-lasting performance in demanding work environments, supporting consistent quality control and accurate pass/fail decisions.

• Knurled, ergonomic grip for fast handling: The knurled outer edge provides a secure grip and quick alignment, helping inspectors perform go/no-go checks with speed and confidence.
• Precise metric fine GO gauge for M16 x 0.5: Specifically designed to verify external threads to the M16 x 0.5 specification, delivering clear pass/fail criteria and reducing rework.
• Hardened steel construction with exceptional wear resistance: Built to withstand daily use in demanding environments, delivering consistent accuracy and a long service life.

By simplifying thread verification, this gauge speeds up quality control, minimizes defects, and helps ensure components fit correctly the first time. Its durable build reduces downtime from tool wear, while the precise Go gauge format provides reliable measurements you can trust across shifts and teams.
