The JBO Thread Ring Gauge (GO) is a precision tool for quickly verifying metric coarse threads. Specifically sized for left-hand M10 x 1.5 connections, it provides reliable go checks to confirm parts meet the required thread dimensions.

Designed for inspectors, machinists, buyers, and hobbyists alike, it supports accurate quality control and smooth assembly by catching mismatches before they reach production or fitment stages. Crafted from hardened steel, this gauge stands up to daily use in busy workshops while preserving tight tolerances.

• Left-hand M10 x 1.5 coarse-thread specification: Precisely sized for LH M10 x 1.5 threads, enabling quick go/no-go checks and confident acceptance of mating parts.
• 6g tolerance for consistent results: The 6g tolerance class ensures stable, repeatable gauge performance across shifts and batches.
• Durable hardened steel construction: Built to resist wear in busy environments, maintaining accuracy over time.

Using this gauge streamlines quality checks, reduces guesswork, and minimizes downtime caused by thread mismatches on left-hand metric coarse connections. It helps you verify size, pitch, and fit quickly, supporting better supplier qualification, faster assemblies, and consistently high-quality results across production runs.
