Is this due to wear? Does that mean the smaller spline would be more likely to wear faster with the fore and aft torque of the drive line?

PDUB, We use a lot of fixtures at work. What I have seen is a chance of pulling threads out with continual use, bolt in bolt out. A splined shaft has a large surface area vs. fasteners I would not think you would see wear on a shaft vs. a bolt. I would not worry.

Helicoils work even better!
