The JBO Thread Ring Gauge GO (Metric Fine) is a precision tool designed to verify the external thread diameter of fasteners and threaded components. It’s ideal for quality-control labs, workshop benches, and production lines that require quick, reliable checks for metric fine threads, including M22 x 1.5. This GO gauge helps confirm that parts will thread properly with mating components, reducing surprises in assembly.

Crafted from hardened steel, this gauge delivers outstanding durability and wear resistance for demanding environments. Its robust construction stands up to daily use, while the straightforward design makes it easy to identify parts that conform to the required standard—supporting efficient QC workflows and precision engineering.

• Durable hardened steel construction: Built to withstand daily shop use, delivering long tool life and maintaining accurate measurements even after thousands of inspections.
• Precise metric fine GO gauge (M22 x 1.5): Provides fast, unambiguous go/no-go confirmation of external thread size, speeding up inspections and reducing rework.
• Right-hand orientation with 6e tolerance: Aligns with standard metric threads and delivers repeatable, reliable results across production runs.

Used effectively, this gauge accelerates quality checks, improves consistency across lots, and minimizes downtime caused by mismatched threads. Its durable construction and precise Go sizing empower teams to make confident, repeatable measurements, supporting smoother assembly, better traceability, and higher overall quality in manufacturing and maintenance environments.
