The JBO Thread Ring Gauge (NoGo) for Metric Coarse threads is a precision inspection tool designed to verify external thread diameters quickly and reliably. Ideal for quality control teams, machinists, and assembly technicians, it ensures M3.5 x 0.6 coarse threads meet required standards before they enter production or assembly. Its NoGo design provides a clear, simple pass/fail indication, helping you identify non-conforming parts at a glance.

Crafted from hardened steel, this gauge is built to withstand the rigors of busy workshops, resisting wear and maintaining accurate tolerances over time. Its Right Hand configuration and 6g tolerance class align with common metric coarse-thread applications, delivering consistent performance across repeated inspections and demanding environments.

• Accurate NoGo verification for M3.5 x 0.6 coarse threads: Quickly confirms external thread diameters against specification, helping prevent mismatches and costly rework.
• Durable hardened steel construction: Designed for long life in active shop settings, maintaining precision after frequent use.
• Right-hand orientation with clear non-conformity indication: Fits standard metric assemblies and delivers fast, intuitive pass/fail results to speed up quality checks.

By using the JBO Thread Ring Gauge, your team can streamline inspection workflows, reduce downtime from incorrect threads, and ensure reliable, repeatable results in every threaded connection.
