Looking for a source for 3" (2 1/2" may work) screws with rubber washers for fastening corrugated roofing to metal purlins. I'm using 2" and in several spots need something a little longer to catch the purlin. Not sure I have the choice of being picky, but if I can get them in green that would be a bonus.
