There is no tension on a pier pin, only shear, and hopefully not much if the
tower is plumb and the guy tensions are equal. The only purpose of an adhesive
in this application is to keep someone from pulling the pin out. Otherwise
epoxy adds nothing to the structural integrity. To illustrate the point (I
don't recommend doing this) you could drop it in the hole and tack weld it to
the tower base only and you would accomplish the goal.

I am far from being a tower expert however I once installed a 160' Rohn 65
tower on an old crankup tower base and I just used anchor concrete from Home
Depot to set the pier pin in an oversized hole. This is different than
epoxying bolts for a free standing tower where you need maximum adhesion.
The base worked perfectly for a number of years until I moved.

I think I have arranged most of the Rohn 45 that I need and have the concrete
base and pier pin. I need to drill a hole for the pier pin and lost the name of
the epoxy (Quikcrete brand?). I know it sets in about 2 days.
Thanks to everyone for the help.
