Treated wood eats them?

Posted by schoolhouse (My Page) on

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?

Bolts, nuts and washers need to be "double galvanized" for the ACQ wood treatment. Indeed, screws need a special coating as well. Our government in a rush to remove arsnic from wood treatments has left us with the current mess. I have sold fasteners and lumber for 25 years. The feds went through my inventory and 12 months of records in a surprise visit to ensure the old pressure treated lumber was no longer retailed. The new treatment has a habit of "eating" my steel racking. I assume homeowners will have failures down the road, leading to deaths and litigation.

Yikes. Thanks for the info.
