Critical Wood Properties Wet vs. Dry Wood Moisture Content If 19% or Less = “DRY” to engineer If above 19% = “WET” The wetter the wood, lower the connection strength Must be compensated for by engineer: Per NDS 10.3.3 “When connections are exposed to wet service conditions in use, reference design values Zinc-plated finish provides standard corrosion resistance. x 4 in. This is the most important thing you’ll want to know in order to select the correct screw. Yeah some fat eye bolts (5/16 maybe even 3/8) are your best bet. The reason for a specialised screw in such circumstances is that wood shrinks and expands depending the temperature around it, and as a result these screws are flexible and will bend before snapping.
