Galling is caused by a transfer of metal from the nut to the bolt (or vice versa) due to high pressure and sometime electrical currents running through the materials. The popular term is seizing.
All our anchor bolts are coated with an anti-seize material when shipped from the factory. Just touch the thread of the bolt in the anchor and the dark gray grease you feel with confirm that the bolts are protected (less now that you removed some of the grease with your finger). However, if you supply your own bolts (e.g. when our bolts are too short for your application), you must apply a suitable anti-seize lubricant.
Use Permatex Nickel version 77164 for STAINLESS STEEL anchors. Use the copper based 80078 for the standard Zinc plated anchors. You can use pastes from other manufacturers; we happen to use Permatex.
