The JBO Thread Ring Gauge (NoGo) is a precision tool for inspecting external threads on UNS right-hand components, specifically sized for 1 3/16 x 16 and engineered to meet class 2A. It enables quick, reliable checks to confirm that threaded parts conform to Unified thread standards, making it ideal for manufacturers, automotive shops, and aerospace suppliers alike.

Crafted from hardened steel, this gauge combines durable construction with precise dimensions. The NoGo design provides an immediate visual and tactile cue when a thread is out of spec, helping you identify non-conforming parts early in the process and ensuring proper fitment and reliable performance in assembled systems.

• Accurate UNS NoGo gauge for 1 3/16 x 16 Right-Hand threads: Enables quick verification of external thread diameter against Unified thread standards, reducing guesswork and ensuring consistent fits in assemblies.
• Rugged hardened-steel construction with knurled edge: Built to withstand daily shop use and provides a secure grip for easy, repeatable measurements.
• Fast go/no-go verification for faster QC: Delivers an immediate pass/fail indication, speeding inspections, cutting downtime, and helping maintain production schedules.

Incorporating the JBO Thread Ring Gauge into your quality control workflow delivers reliable, repeatable measurements that improve thread compatibility across parts, reduce rework, and support confident decisions when selecting or approving threaded components.
