The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed to verify the maximum outside diameter of metric threads on components. Specifically tuned for M68 x 4, 6g right-hand threads, it delivers quick, unambiguous pass/fail results to support accurate quality control. Use it in incoming inspection, in-process checks, or final QC to ensure parts meet the required specification.

Built from hardened steel for long life, the gauge resists wear and maintains dimensional accuracy even in busy workshop environments. The knurled outer edge provides a secure grip for quick handling and alignment, making inspections reliable and efficient, even when you’re wearing gloves.

• Precise NoGo verification for M68 x 4 Right-Hand, 6g threads: Quickly confirms the maximum external thread diameter, enabling fast pass/fail decisions and reducing rework in QC.
• Hardened steel construction for durability: Designed to withstand daily use, resisting wear and maintaining accuracy over time in demanding settings.
• Ergonomic, knurled design for secure handling: Easy to grip and align, even in tight spaces or with PPE, speeding up inspections and reducing slips.

In daily use, this gauge helps you streamline quality control, shorten inspection cycles, and improve consistency across parts and assemblies. By reliably verifying the M68 x 4, 6g right-hand specification, it supports smoother production flows, better compliance with standards, and higher overall performance in your manufacturing or workshop operations.
