2x wood nailers to steel beams

[wl2o8]

I am using a double 2x P.T. wood nailer to steel beam detail when supporting wood framing on steel. I use a double plate so that common box nails can be used without nailing through to the steel. Does anyone have any good suggestions for connecting the wood nailer to steel? I have used 5/8" bolts at 24" o.c. staggered in the past, but the bolt heads will be in the way if not recessed.

If you are attaching one wood plate by itself, you can use powder actuated fasteners by Hilti or similar. The information I received was they could be driven into a 1/2" thick steel flange. I wouldn't use them where a plastic hinge was expected in the beam (seismic).

We have used the Hilti power fasteners on many projects joining steel with wood lagging. I only uses one layer of wood (two inches thk) to reduce the bending/hinge effect. Just specify the stub nails to reduce the interference problem. See the Hilti web site for spacing.
