The JBO Thread Plug Gauge is a precision inspection tool designed to verify trapezoidal threads in holes. Built for manufacturing, automotive, aerospace, and maintenance teams, it helps ensure threaded components meet exact size and fit requirements. With its Go/No-Go design, inspectors can quickly confirm conformance and move on to the next part with confidence.

Sized for right-hand trapezoidal threads, this gauge features a trapezoidal thread profile described as 7H and Tr. 10 x 2. The compact tool offers reliable, repeatable checks and a durable construction suitable for busy shop floors and quality labs.

• Two-end Go/No-Go design: Quickly determine if a hole’s trapezoidal thread meets spec. The Go end confirms acceptable engagement, while the No-Go end detects undersized or out‑of‑tolerance holes, reducing guesswork and rework.
• Precise trapezoidal thread profile (7H, Tr. 10 x 2): Calibrated to the standard trapezoidal size and tolerance, ensuring consistent, repeatable checks across parts and suppliers.
• Durable, user-friendly construction: Metal body with a knurled grip provides secure handling and long life in demanding workshop environments, even with gloves or oily hands.

With the JBO Thread Plug Gauge, you gain faster quality checks, reduced downtime due to misfitting parts, and more reliable thread verification for critical assemblies. The Go/No-Go design delivers clear, actionable results on the shop floor, while the precise trapezoidal profile supports consistent performance across jobs and teams.
