JBO Thread Plug Gauge (NoGo) - UNS - Right Hand - 2B - 1 5/8 x 8

The JBO Thread Plug Gauge (NoGo) is a precision inspection tool designed to verify threaded holes to Unified thread standards. Sized for UNS right-hand threads, 2B tolerance, and a 1 5/8 x 8 specification, it’s an essential instrument for quality control in manufacturing, automotive, and aerospace environments. The NoGo design lets you quickly identify holes that do not meet spec, helping prevent mismatched assemblies and costly rework.

Built for daily use in busy shops, the gauge features a durable metal body and a textured knurled surface for a secure grip. Its compact form makes it easy to handle in tight spaces while delivering repeatable, reliable readings.

• NoGo design for fast conformance checks: Quickly confirms whether a threaded hole is within tolerance and identifies non-conforming holes, speeding inspections and reducing downtime.
• Accurate UNS Right Hand 2B sizing: Precisely matches the UNS right-hand thread form with 2B tolerance, ensuring reliable readings for 1 5/8 x 8 threaded holes.
• Durable knurled body for secure handling: Textured grip provides confident control and consistent measurements, even in gloves or busy work environments.

Using the JBO Thread Plug Gauge (NoGo) simplifies your quality checks, shortens inspection times, and improves confidence across production and maintenance tasks. By clearly indicating non-conforming holes, it helps prevent misfits, reduces rework, and maintains consistent assembly performance on parts used in high-stakes applications.
