Products / SFS #14 Dekfast Phillips Head Fastener

The #14-13 Dekfast is a #3 Phillips-drive roofing screw with a low-profile recessed truss head, intended for attaching insulation and membrane to steel and wood decks, and with a 3/16 in. carbide pre-drill, to structural concrete. It carries a cathodic epoxy e-coat and is listed in lengths from 1-1/4 in. to 12 in. The data sheet prints 15/15 Kesternich cycles per FM 4470 and 800 hours of salt spray per ASTM B117, and notes the truss head can be used for clip attachment where head height matters.
