The JBO Thread Plug Gauge is a precision right-hand go/no-go tool designed to quickly verify threaded holes against Unified thread standards. It’s a practical choice for manufacturers, automotive shops, and aerospace assembly where accurate thread validation matters.

With meticulous design and precise dimensions, it enables fast, repeatable inspections of Pg 11 x 18 hole sizes, helping ensure proper fitment and reliable performance across assemblies.

• Go/No-Go Design for Quick Conformance Checks: Enables fast pass/fail decisions, reducing guesswork and preventing misfits during assembly or quality checks.
• Unified Thread Standards Verification: Precisely checks threaded holes against standard Unified specifications to help maintain consistent fit and function across parts.
• Right-Hand Orientation with Knurled Grip: Designed for comfortable, secure handling on busy shop floors, supporting reliable measurements over repeated use.

This plug gauge helps streamline quality control by providing clear pass/fail indications on threaded holes during in-process checks or final inspection. By catching non-conforming threads early, you reduce downtime, rework, and potential assembly issues, while maintaining consistent results across parts and batches. Its precise Pg 11 x 18 sizing supports reliable, repeatable measurements, so your team can trust results and move quickly through workflows on the shop floor or in the QA lab.
