The JBO Thread Ring Gauge (NoGo) for UNJC external threads is a precise, hand-held inspection tool designed to verify thread diameters quickly and reliably. Built for engineers, inspectors, and machinists across manufacturing, automotive, and aerospace sectors, it helps confirm that external threads conform to Unified standards. Its NoGo design makes non-conforming threads immediately identifiable, supporting fast pass/fail decisions on the shop floor. Crafted from hardened steel, this gauge is made to withstand daily use in demanding environments.

• No-Go design for fast conformity checks: Quickly identify out-of-tolerance threads, reducing inspection time and preventing misfits in assemblies.
• Hardened steel construction for durability: Resists wear through frequent handling, preserving measurement accuracy and extending the tool’s life in busy workshops.
• UNJC, Right-Hand, 3B, 1/4 x 20 sizing: Aligns with common external thread specs, simplifying setup and ensuring measurements match standard threads for consistent results.

With the JBO Thread Ring Gauge NoGo, you can streamline quality checks, tighten control over threaded components, and keep production moving smoothly. Its reliable design supports accurate inspections, reduces rework, and gives you confidence that fittings and fasteners will perform as intended in critical applications.
