The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed to verify external metric coarse threads. Specifically tailored for M11 x 1.5 right-hand threads with a 6g tolerance class, this NoGo gauge helps quality teams, machinists, and inspectors quickly determine whether a threaded component meets the defined limits and is fit for assembly.

Crafted from hardened steel, the gauge delivers durable, wear-resistant performance in busy workshops and production environments. Its straightforward design supports fast, reliable checks, making it suitable for both seasoned inspectors and occasional shop users who need clear, actionable results without guesswork.

• Durable hardened steel construction: Built to withstand daily use in demanding environments, delivering long-lasting accuracy and wear resistance so you can rely on consistent checks shift after shift.
• Precise NoGo reference for M11 x 1.5 right-hand threads (6g): Provides a clear go/no-go verdict against the specified metric coarse thread, ensuring components meet the exact limits for reliable fitment.
• Fast, user-friendly go/no-go verification: Simple to use for quick inspections, helping reduce downtime by promptly identifying non-conforming parts and keeping workflows flowing.

Using the JBO NoGo gauge in your QC process helps standardize thread inspection, improves inspection throughput, and supports consistent, high-quality assembly results. Its durable build and clear, repeatable checks give you confidence that metric coarse threaded connections will perform as intended in the final product.
