deck surface layer fastening

is it OK to use a framing nailer with 2-3/8 hot-dipped galvanized nails to fasten 5/4" decking boards to joists?

thanks

yesir, Sika... that stuff is ridiculously solid.

the two girders are both doubled up 2x8 and one rests on 4, the other on 3 3ft deep concrete piers that are all 12" in diameter. since they needed to be elevated some because of the overall deck height, i used 6x6 posts anchored into the piers with those very expensive decking connectors ($20 OMG).

i am using more than two piers/posts for the girders because they are 2x8 but span more than 8 ft (136"). so the load balancing is pretty darn solid. the one that uses 4 supports the stairs, hence the extra one.

thanks for all your help.

:thumbsup:

deck screws should do the trick :wink: typically brown, green, or stainless. stainless obviously the longest lasting (and most expensive) option...
I often use trim heads, but depends on the type of decking.



there are fancier brand-name screws out there too like GRK, split-stop, etc..

I disagree.
Actually sika anchoring adhesive is approved for only short term load and it should not be used in sustained tensile loads.
Now he's using a carriage bolt that is smooth and with no "deformation" in other words he's using a smooth bar not a "deformed" bar or rebar.
What do you think it happens over time with expansion and contraction of concrete and smooth steel?
Rood loses bond from the anchoring adhesive and it results in a 0 tensile bond to the substrate.
Now in his situation deck is tied to the opposing shed and there is no worries.
But if he had used an anchoring adhesive on a 2 story porch that attaches to the concrete structure it would be a different story.
