2 7/8" sq, 24 gauge, fender / roof insulation washer
2 7/8" SQ, 24 gauge, FENDER / ROOF INSULATION WASHER:
Sale is for fifty ( 50 ) washers which is one ( 1 ) lot. These washers were made for securing thermal insulation board to flat roof steel decking via a self drilling & tapping screw ( there should be a listing for them "ROOF DECK SCREW" ). Steel decking is normally 22 gauge steel sheet metal, but these washers are only securing flat insulation boards so they are lighter ( 24 gauge ). Each washer is ribbed so they are strong. These washers are plated with an aluminum & zinc alloy to give good corrosion resistance. These washers conform to Factory Mutual ( FM ) requirements for ROOFING use, but they can be used anywhere you need them. The FM requirements covers corrosion resistance and securement strength. These washers work well to secure soft / crushable materials like thermal insulation. These washers have a 1/4 inch diameter center hole, and they are 2 7/8 inches square. The Accutrac System by Buildex uses these washers; you stand upright using the Accutrac equipment which reduces fatigue on workers. I have found these washers ideal for securing wood fiber building board on wood frame construction; the fastener heads do not sink / pull through the board as often occurs without a washer to spread the securement.
