The JBO Thread Ring Gauge (GO) is a precision tool for quick, reliable verification of external metric threads. Designed for professionals across manufacturing, quality control, and maintenance, this GO gauge checks components against the exact M80 x 1.5 fine-thread specification within the 4h tolerance. Its right-hand orientation makes it ideal for standard threaded parts encountered on the shop floor, ensuring consistent acceptance criteria on every inspection.

Crafted from hardened steel, the gauge delivers exceptional durability and long service life in demanding environments. The intuitive ring design provides clear, on-the-spot identification of conforming parts, helping teams speed up inspections without sacrificing accuracy.

• Precise GO Gauge for Metric Fine Threads: Verifies external M80 x 1.5 threads to the 4h tolerance, enabling fast, accurate thread checks on the spot.
• Hardened Steel Construction: Built to withstand daily use and resist wear, preserving dimensional integrity over many cycles.
• Fast, Clear Pass/Fail Checks: Simple alignment and unambiguous indication let operators approve or reject components in seconds, reducing downtime and rework.

Using this gauge on the production line or in the workshop improves workflow by delivering reliable, repeatable measurements, helping you meet tight specifications, maintain consistent quality across batches, and keep projects on schedule with confidence.
