The JBO Thread Plug Gauge is a precision go/no-go inspection tool built to verify UNC threaded holes quickly and reliably. Sized for 3/4 x 10 UNC with a Right-Hand orientation and 3B tolerance, it aligns with standard Unified thread specifications for components across manufacturing, automotive, and aerospace environments.

The two ends deliver separate checks: the Go end confirms the thread hole accepts the minimum specified engagement, while the No-Go end ensures the hole does not exceed maximum limits. The ergonomic, knurled body provides a secure grip for repeated use in busy shops, delivering consistent results when inspecting multiple parts.

• Go/No-Go verification at a glance: Quickly determine if a threaded hole is within tolerance by comparing against Go and No-Go ends, reducing guesswork and rework.
• Standard UNC 3/4-10 Right-Hand, 3B tolerance: Precisely matched to common thread standards for reliable interchange with fasteners and components across industries.
• Ergonomic, durable two-ended design: Knurled grip and robust construction support daily use, long life, and repeatable measurements in demanding environments.

By using the JBO Thread Plug Gauge, you streamline your threaded-hole inspections, shorten setup times, and improve overall part quality. Its straightforward pass/fail feedback helps you approve good parts fast and identify non-conforming holes early, reducing downtime and scrap while boosting confidence in assembly and maintenance workflows.
