The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed to verify external metric thread diameters. It’s ideal for engineers, quality inspectors, machinists, and workshop teams who need fast, reliable checks to ensure parts meet exact specifications for fit and performance.

Crafted from hardened steel, this NoGo gauge is built to endure the rigors of busy workshops and demanding environments. The metric fine thread specification—M100 x 3 on right-hand threads with a 6g tolerance—provides a clear, repeatable standard for accepting or rejecting components, helping your quality control process stay consistent over time.

• Durable hardened steel construction: Designed for longevity in daily use, resisting wear and maintaining accurate measurements even after repeated insertions and removals.
• Precise NoGo gauge for metric threads (M100 x 3, 6g): Delivers quick, unambiguous pass/fail results, reducing inspection time and ensuring parts conform to the exact thread size and class.\n
• User-friendly, right-handed design: Knurled edge and clear markings make handling easy and orientation consistent, aiding fast setup and reliable checks on the shop floor.

Incorporating the JBO NoGo Ring Gauge into your QC workflow helps you confirm external thread compliance at a glance, minimize rework, and accelerate acceptance testing. Its robust construction and straightforward use give teams confidence that threaded components meet the specified M100 x 3 right-hand 6g standards, supporting smoother assembly, tighter quality control, and greater overall efficiency.
