For outdoor humid, hot central Florida. Strong structural concrete screws.

Im attaching simposon H10S and LGT2 straps to my rafters and cinder block walls. Im using simpson screws to attach to the rafters, however simpson makes no outdoor concrete screws and has no suggestions. So, Im looking for the best reasonably priced outdoor concrete screws for use in central Florida.

Thanks,
Pa?

These are available in stainless steel Order Tapcon Screws Today | ConcreteFasteners.com (http://www.concretefasteners.com/anchors-fasteners/tapcon-screw/pricing.aspx?gclid=CPiosJXm18ACFehaMgodcR8A7A#) but I am not certain screwing into cement block will do much. I assume you are trying to add some hurricane strengthening but a cement block wall isn't much of an anchor point.
