When verifying rod end engagement, what does it indicate if threads are visible in the inspection hole?

• A. Engagement is achieved
• B. Engagement is not achieved
• C. The rod end is missing
• D. The hole is blocked

Answer: (A)

Folding in the concept of proper engagement, you verify rod end engagement by checking how far the threaded portion has threaded into the mating part. If you can see threads through the inspection hole, that means the rod end has been threaded in to the required depth and the engagement is achieved—the threads are still present, indicating the joint is seated and secured. If the hole showed no threads, you’d likely have insufficient engagement, and the connection could loosen under load. The other options aren’t applicable: a missing rod end would leave the hole incomplete, and a blocked hole would prevent seeing any threads at all.
