I go to http://www.fastenal.com/ for real hardware but I don't know if
they have exactly what you desire.

McMaster Carr at mcmaster.com has a lot of hardware too.

Is the SHAFT of these bolts splined near the head? Never seen those,
but it sounds like a good idea.

There are ones with the serrations on the bottom of the head itself.
McMaster has those, they're pretty common.

Be positive of the correct "grade" of bolt that you should be using for a
tower.
Avoid check surplus bolts of unknown origin - bad event - bolt shears -
and it was a check Far East knock-off, incorrectly marked.

All bolts may have questionable origin. In addition to the bolt`s shear
strength, it may loose its head at too low a torque.

Use a torque wrench to measure the point at which several bolts lose
their heads.
