The JBO Thread Ring Gauge (GO) – Metric Coarse is a precision go gauge designed to quickly and reliably check external metric coarse threads. It helps quality teams, machinists, and assembly professionals confirm that threaded parts will mate correctly with mating components, specifically for the M1.6 x 0.35 size. With its GO designation and a right-hand orientation, this gauge provides straightforward, decisive feedback to keep production moving.

• Accurate GO standard for metric coarse threads: Delivers clear pass/fail checks on external threads, helping you verify parts meet the M1.6 x 0.35 specification and fit with mating components.
• Hardened steel construction for long tool life: Built to withstand frequent use in demanding environments while maintaining precise, durable performance over time.
• Right‑hand design and user‑friendly handling: Compact, easy to align in tight spaces, enabling fast setup and repeatable checks across multiple parts and jobs.

Using this gauge streamlines quality control by delivering reliable, repeatable measurements that minimize guesswork and downtime. It helps you quickly verify thread compatibility, reduces rework, and supports consistent results across batches, ultimately improving throughput and confidence in every threaded assembly.
