Yes, perhaps someone who can be objective?Are you a competent luthier? Can a competent luthier please chime in on this. I am not a pro but I have alot of experience with bolts and threads. Truss rods have a pretty fine thread, 1/4" is plenty to provide a secure connection.
Don't discount the fact that I have many years (40) of playing under my belt, and adjusted many truss rods. I also happen to be a machinist for a large defense contractor. I know a little about threads.
