The JBO Thread Ring Gauge (NoGo) is a precision tool for verifying external metric coarse threads. It’s ideal for quality control, manufacturing, and maintenance teams that need fast go/no-go checks to confirm components meet required standards.

Crafted from hardened steel, this gauge resists wear in demanding work environments, delivering reliable performance across repeated inspections and long service life.

• Precise NoGo Verification for Metric Coarse Threads: Quickly determine non-conforming parts with a clear pass/fail result, reducing inspection time and rework.
• Rugged Hardened Steel Construction: Built to withstand daily use in busy workshops, delivering long-lasting performance and repeatable results.
• Size-specific, Right-Hand M52 x 5 (6h): Ensures correct alignment and consistent checks for standard metric coarse threads, supporting reliable fitment verification.

The JBO Ring Gauge streamlines quality control by providing a straightforward, repeatable method to verify thread diameters. Its durable construction stands up to shop-floor wear, while its size-specific design ensures you’re testing against the exact thread you intend to use. By enabling quick identification of non-conforming parts, it helps minimize downtime and improve overall accuracy in thread assembly and performance of critical equipment.
