Our engineers have approved the use of a box bolt to attach the base to the pole.
Hold the large hex body with a wrench and tighten the smaller hex bolt with an impact or ratchet until the small hex breaks off at 57 ft/lbs of torque.
A box bolt works much like a rivet. It is inserted into the hole in the base and pole.
The outer shell is held constant when the inner bolt is tightened.
The expansion nut is pulled into the shell and the bolt expands inside the metal.
Comments will be approved before showing up.
