Treated wood eats them?
My builder says one reason for the high quote on building my pergola or porch in the orchard is the $125 worth of special screws and bolts needed for the treated wood. He says normal screws will be "eaten". I can see the need for the use of the bolts into the treated 4X4 skids but are the special screws needed for the floorboards? I prefer the look of nails in the floor actually but apparently that's not his idea. Anyone had screws eaten by TW?
