The JBO Thread Ring Gauge (GO) in metric fine is a precision inspection tool designed to verify external thread diameters for metric threads. Suited for engineers, machinists, quality control teams, and maintenance staff, it ensures that M18 x 1.5 threads meet the required minimum size and pitch in a reliable, go/no-go check. Built for right-hand threads and 6e tolerance, this gauge helps streamline acceptance testing and keeps parts within specification.

• Metric fine GO gauge for M18 x 1.5, 6e: Confirms minimum external thread size and pitch to ensure components will thread properly and meet exacting standards.
• Hardened steel, wear-resistant construction: Delivers long service life in busy workshops, resisting wear and maintaining accuracy over thousands of checks.
• Fast, intuitive inspection tool: Enables quick pass/fail decisions with a smooth, consistent ring design that minimizes handling and setup time.

Using the JBO Thread Ring Gauge helps you tighten quality control, reduce rework, and keep production flowing smoothly. Its durable build and precise dimensions provide repeatable results across shifts and operators, giving your team a confident, efficient way to verify threaded components before they move to assembly or seating operations.
