The JBO Thread Plug Gauge provides a reliable way to check M30 x 1.5 metric fine threads during production and inspection. Built for right-hand threads with 6G tolerance, it helps machinists, quality teams, and assembly technicians confirm that threaded holes will accept mating parts correctly without time-consuming manual measurements.

• Go/No-Go Design: Lets you verify thread fit in seconds by checking both limits with a single tool, reducing inspection steps and helping avoid assembly issues later.
• Hardened Steel Construction: Maintains accuracy over repeated use, resisting wear from daily checks in workshops and production lines.
• Metric Fine Thread Focus: Matches the exact requirements of fine-pitch applications where standard coarse gauges would not provide the needed precision.

This gauge supports consistent quality control so parts fit together properly on the first attempt, cutting down on rework and helping maintain smooth workflows from machining through final assembly.
