The JBO Thread Ring Gauge (GO) is a precision go gauge for verifying external threads in metric fine pitch. Specifically matched to M85 x 1.5 left-hand threads, it’s a reliable tool for engineers, machinists, quality teams, and workshop technicians who need fast, accurate conformance checks.

• Accurate Go gauge for M85 x 1.5 LH threads: Quickly verify external thread diameter and alignment to spec with a clear go/no-go result, reducing inspection time and rework.
• Hardened steel construction: Built to withstand daily use in busy workshops, resisting wear and maintaining calibration for long tool life.
• User-friendly design for fast conformance checks: Easy identification of properly threaded components supports streamlined quality control and minimizes setup errors in busy environments.

In daily QC workflows, this gauge speeds inspections, minimizes downtime, and delivers consistent results across parts and batches. By providing a reliable go/no-go check for M85 x 1.5 LH threads, it helps your team maintain quality, reduce rework, and keep production on schedule.
