The JBO NoGo Thread Ring Gauge (Metric Fine) is a precision tool designed to verify external thread diameters on fasteners, shafts, and machined components. Specifically calibrated for metric fine threads, this gauge tests the M60 x 2 size with a 4h tolerance and a right-hand orientation, delivering a reliable go/no-go check in a single step. It’s ideal for quality control teams, machine shops, and assembly lines that require quick, confident acceptance decisions.

Created for everyday use, the gauge combines exact dimensions with a simple, durable design. The NoGo configuration enables rapid identification of parts outside tolerance, helping cut inspection time and prevent downstream rework. Crafted from hardened steel to resist wear, it maintains accuracy through heavy use and busy environments, ensuring consistent measurements you can rely on across jobs.

• Go/No-Go inspection for external threads: Quickly confirm that an M60 x 2 thread meets the 4h metric fine spec or flag out-of-tolerance parts, reducing rework and production delays.
• Hardened steel construction for durability: Built to withstand daily use in demanding workshop settings while preserving measurement accuracy over time.
• Right-hand, metric fine design for reliable compatibility: Precisely matched to standard right-hand metric threads, ensuring consistent fit and straightforward setup across jobs.

With the JBO NoGo Thread Ring Gauge, you’ll streamline quality control by delivering fast, decision-ready measurements on external threads. Its robust construction and precise sizing help minimize downtime, shorten inspection cycles, and improve overall workflow reliability across manufacturing or maintenance tasks. Use it to verify parts at receipt, during in-process checks, or before assembly, ensuring threaded components meet exact specifications every time.
