Yes, the larger thread diameter gives more area in shear around the bolt,
therefore the ½ “ bolt connection will take more load.  Also, the larger
thread (13 per inch, rather than 20 per inch) also makes each thread a bit
stronger.

1/2-13.  Makeup torque is very important.

 What's stronger in tensile strength?

 

 1/4-20 thread tapped into a 1/4" aluminum plate?

 

 or
