Hi to all,<br /><br />Setting up my new to me Tim's 16x54 commercial flat and when I redo the wood floor I was wondering what is the best way to mount it to the ribs. I checked at my local fastner supplier they do not have a s/s flat or round head screws with drill bit tips. (self taping) So I guess it's drilling and screwing a screw in them. What size screw would yall recommend? Ribs are 14" on center. It has 3/4 plywood now and I'm thinking on changing it to 1/2" to lighten it up.<br /><br />Any input would be appreciated.<br /><br />Beck
