The JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 4h - M3 x 0.35 is a precision external-thread gauge used to verify the outside diameter of metric threads on fasteners, fittings, and threaded components. It enables quick, reliable pass/fail checks for quality control, making it a trusted tool for engineers, inspectors, machinists, and maintenance teams.

Built from hardened steel, this gauge offers durability and wear resistance for long service life in demanding work environments, ensuring consistent measurements even after heavy use.

• Accurate NoGo verification for M3 x 0.35 threads: Helps ensure components meet exact outer thread size, reducing fit issues and rework.
• Hardened steel construction for long service life: Delivers durable performance and maintains measurement accuracy in busy workshops.
• Right-Hand, Metric Fine design for quick, consistent checks: Aligns with standard metric fasteners and streamlined inspection workflows, enabling reliable pass/fail decisions with minimal setup.

Using this gauge, you can speed up thread inspections, lower scrap and rework, and improve overall assembly quality. The rugged design stays accurate through routine use, while the clear, straightforward check process helps teams maintain consistent results across shifts and projects.
