The JBO Thread Plug Gauge (NoGo) is a precision inspection tool designed to verify internal threads in holes against Unified Thread Standards. Ideal for manufacturing lines, automotive shops, and aerospace QA, it provides a fast, reliable way to confirm that threaded holes meet required specifications before parts move to the next stage.

Sized for UNS, right-hand threads with a 2B tolerance class, and a 1 7/8 x 12 dimension, this NoGo gauge delivers clear, practical go/no-go feedback. Use it to quickly identify non-conforming threads, helping you prevent misfits and costly rework in critical assemblies.

• NoGo Design for Fast Conformance Checks: Quickly identify non-conforming threads with a clear pass/fail indication, reducing inspection time and preventing assembly delays.
• Exact UNS Right‑Hand 2B Size (1 7/8 x 12): Built to the specified standard, ensuring consistent measurements that align with your quality and process controls.
• Durable, Precision‑Machined Construction: Robust design supports repeated use in busy shops, delivering reliable results over time and supporting consistent quality across inspections.

This gauge helps streamline quality workflows by providing dependable thread verification, lowering scrap rates, and accelerating throughput without sacrificing accuracy. By using the JBO Thread Plug Gauge (NoGo), you can trust that threaded holes will fit correctly in assemblies, meet spec, and perform as intended in demanding applications.
