JBO Thread Plug Gauge (Go/NoGo) - NPTF - Right Hand - 1 x 11.5

The JBO Thread Plug Gauge (Go/NoGo) for NPTF, Right Hand, 1 x 11.5 is a precision inspection tool designed to verify internal threads in holes against exact NPTF specifications. Suitable for manufacturing, automotive, and aerospace environments, it helps quality teams and machinists confirm thread conformity quickly and reliably.

Its Go/NoGo design provides fast pass/fail feedback on each hole, enabling faster setup, reduced rework, and more consistent results across shifts and operators. The right-hand configuration matches common threading in critical assemblies, helping you maintain tight tolerances with confidence.

• Go/NoGo quick-check design: Quickly determine thread conformity—the Go end confirms a compliant hole while the NoGo end ensures non-conforming threads are detected, delivering a clear pass/fail signal to speed up inspections and reduce guesswork.
• Precision NPTF right-hand dimensions: Machined to exact NPTF right-hand thread specifications (1 in nominal, 11.5 TPI) to ensure repeatable, reliable measurements across lots and operators.
• Durable, easy-to-handle construction: Textured knurling on the body provides a secure grip, while robust construction withstands daily use in demanding shop environments.

Using the JBO Thread Plug Gauge helps streamline quality checks, improve assembly reliability, and protect critical components from misfit threads. The exact Go/NoGo verification saves time, reduces downtime from incorrect threads, and delivers consistent results across teams—so you can trust every threaded connection you assemble or inspect.
