The JBO Thread Ring Gauge GO Metric Fine LH 6g M22 x 1.5 is a precision tool designed to verify external thread diameters with consistency and ease. It’s suitable for a wide audience—from engineers and buyers to tradespeople and hobbyists—helping you confirm that a threaded component matches the M22 x 1.5 standard and 6g tolerance.

As a GO gauge, it provides a clear pass/fail check that supports reliable quality control across production, assembly, and service tasks. Made from hardened steel, it resists wear and deformation in busy workshop environments, delivering long-lasting accuracy you can count on.

• Go gauge design for fast conformity checks: Quickly verify that parts meet the M22 x 1.5 LH thread specification with a straightforward pass/fail indication, speeding up inspections and reducing guesswork.
• Hardened steel construction for lasting durability: Built to withstand daily use in demanding environments, resisting wear so the gauge maintains accuracy over time.
• Left-hand metric fine compatibility (M22 x 1.5, 6g): Specifically engineered for left-hand threads and fine-pitch applications, ensuring precise, reliable acceptance of LH components without extra tools.

With the JBO Thread Ring Gauge in your toolkit, you gain a dependable, time-saving solution for thread inspection. It helps streamline quality-control workflows, reduce rework, and promote consistent results across batches, giving you confidence in every threaded part you measure.
