Where do I find the galvanized bolts with the spline under the head to
assemble a 3-leg tower??
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.
