The JBO Thread Ring Gauge GO for Metric Fine threads is a precision external-thread go gauge designed for M15 x 1 right-hand threads (6e). It helps engineering, manufacturing, and QC teams quickly verify thread size and pitch to ensure parts meet spec on the spot.

• Precise Go Gauge for M15 x 1 Metric Fine Threads: Delivers accurate pass/fail checks for the external thread diameter and pitch, reducing guesswork and preventing mismatched parts in assembly.
• Durable Hardened Steel Construction: Built to withstand daily workshop use, resisting wear and maintaining dimensional accuracy over many inspections for long tool life.
• Fast, User‑Friendly Verification: Intuitive design provides clear, quick verification results with minimal setup, speeding quality checks on busy production lines.

With the JBO GO gauge, you gain a reliable, repeatable method to validate threads, helping you shorten inspection cycles, improve first‑pass yields, and maintain consistent thread quality across components and batches.
