The JBO Thread Plug Gauge (GO) - Metric Fine - Right Hand - 6H - M72 x 1 is a precision GO plug gauge used to verify internal threads in threaded holes. Designed for quality control, machining, and maintenance, it quickly confirms whether a hole will accommodate the intended fastener.

Built from hardened steel, this gauge resists wear and maintains accuracy even with frequent use in demanding workshops. The metric fine thread and right-hand orientation align with standard practice, ensuring reliable measurements and easy integration into existing inspection routines. With its 6H tolerance, it supports consistent results across parts and batches.

• Exact M72 x 1 Metric Fine Go Gauge: Verifies internal thread size precisely so holes accept fasteners consistently and reduces guesswork during assembly and QC checks.
• 6H Right-Hand Tolerance: Standardized tolerance guarantees repeatable results across parts, suppliers, and batches—minimizing fit issues in production.
• Hardened Steel for Durability: Made to endure daily shop use, resisting wear and preserving accuracy even after repeated insertions and extractions.

By providing a clear go condition for M72 x 1 holes, the gauge helps you verify thread integrity quickly, minimize rework, and keep production moving smoothly—from engineering labs to workshops to maintenance bays.
