The JBO Thread Plug Gauge is a precision inspection tool designed to verify trapezoidal threaded holes with go/no-go accuracy. This right-hand gauge is calibrated to Tr. 14 x 3 with a 7H tolerance, making it ideal for fast, reliable checks on threaded components.

Used across manufacturing, automotive, and aerospace environments, it enables quick confirmation that a hole meets the required trapezoidal thread specifications, ensuring proper fitment and reducing the risk of mismatched parts.

• Go-No/Go conformance for trapezoidal threads: The go/no-go feature lets technicians instantly identify conforming vs. non-conforming holes, speeding inspections and reducing rework.
• Right-hand orientation for consistent results: Specifically configured for right-hand trapezoidal threads, ensuring orientation consistency across inspections and assemblies.
• Precisely sized Tr. 14 x 3 with 7H tolerance: Delivers repeatable, documented measurements that support quality control and traceability across production runs.

With the JBO Thread Plug Gauge, your inspection routine becomes faster and more reliable. By delivering clear go/no-go results, it reduces guesswork during setup and maintenance, supports tighter quality control, and helps your team achieve consistent thread engagement across parts and assemblies.
