I'm re-planking my deck and shoring up some of the substructure while I'm in there. The beams are side-mounted to the posts like this (from dca 6):
This is obviously non-ideal, but is impractical to replace. I'm spot-checking the existing lag bolts and am finding some surface rust (not bad after 30 years), so in an abundance of caution I'm going to replace them with new ones.
Galvanized is what appear to be recommended, with stainless steel being preferred if you have the budget. However, what about the Hillman Deck Plus lag line? The only information I can find on them is their own marketing material claiming they are 2x more corrosion resistant than galvanized. Is this legit? Or should I stick with Galvanized or stainless steel?
