The JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 4h - M45 x 1.5 is a precision inspection tool designed to verify external thread diameters quickly and reliably. Ideal for inspectors, machinists, and quality teams, it helps confirm that threaded parts meet exact standards before assembly or acceptance.

Forged from hardened steel for excellent wear resistance, the gauge maintains accurate measurements through repeated use in demanding environments, delivering consistent results you can trust.

• Precise GO checks for external threads: Quickly determine whether a threaded part meets the GO tolerance, speeding up inspections and reducing bottlenecks on the shop floor.
• Durable hardened steel construction: Built to withstand daily handling, wear, and routine cleaning without losing dimensional accuracy over time.
• Metric fine, right-hand M45 x 1.5 with 4h tolerance: Specifically matched to metric fine-thread standards, ensuring consistent compatibility with mating components and reducing the risk of mismatches.

Using this GO ring gauge helps streamline quality control by providing clear go/no-go results, supports reliable thread mating in assemblies, and lowers the risk of returns due to improper threading. The robust construction minimizes downtime and replacement costs, while the precise M45 x 1.5, right-hand threads ensure dependable performance across production runs.
