Description

The JBO Thread Plug Gauge is a trapezoidal go-no-go gauge designed for precise inspection of threaded holes and mating parts. It is built for right-hand threads and features 7H tolerance with Tr. 24 x 5 sizing, making it ideal for verifying conformance to trapezoidal thread standards. Used across manufacturing, automotive, and aerospace environments, it helps ensure threads meet Unified thread standards quickly and reliably.

With a simple go/no-go design, you can identify conforming versus non-conforming threads at a glance, reducing guesswork and rework. The compact, dual-ended construction and knurled body deliver secure handling and long life in busy shop floors.

  • Fast go/no-go verification: Quickly determine whether a threaded hole meets the trapezoidal Tr. 24 x 5 size and 7H tolerance, delivering clear pass/fail feedback and speeding inspections.
  • Rugged, ergonomic design: Knurled grip and sturdy metal ends provide secure handling and durability in day-to-day use.
  • Precise, standard-aligned sizing: Manufactured to tight trapezoidal thread specs (Tr. 24 x 5) with 7H tolerance, ensuring repeatable measurements and easier supplier qualification.

Using this gauge helps you streamline quality checks, improve first-pass acceptance, and protect assembly performance by ensuring every threaded hole or boss is within spec. It reduces downtime, minimizes waste, and delivers reliable results across your production line.
