Are these suitable for attaching the flange of a steel deck railing post through the deck floor boards and into the joists? Do they need to be isolated from the steel?
Asked by: Gary
I don't see why not. I would add a nice fat washer to prevent it from driving through thin steel (1/16" or less) which these fasteners can do as you will find out. You could add some kind of protective gook on them to prevent corrosion after installation. They will drive clean through a 2 x 4 if you don't back off the drill in time. I was using a low rpm 1/2" drill. JayJayKay

Are these ok to use with pressure treated framing lumber?
Asked by: rob
Hi Rob, this is Robert from the GRK product team. GRK's Rugged Structural Screws are coated with a Climatek coating that delivers superior corrosion resistance, allowing the screw to be used in both interior and exterior applications as well as pressure treated lumber.
