A fastening disk for use in attaching sheet material to a substrate, comprising: (a) a disk plate with a substantially discoid concave proximal surface for positioning facing the sheet material to be attached, (b) concentric inner and outer tubular posts extending from the distal surface of the disk plate, (c) radial struts connecting the inner and outer posts, and (d) radial vanes on the distal surface of the disk plate between the outer post and the periphery of the disk plate, the disk being compressible to reduce the concavity of the disk plate. Also, means for attaching sheet material to a substrate comprising said fastening disk, a pliable gasket for positioning between the proximal surface of the disk plate and the sheet material, and a compression/retention means for insertion in the inner post of the disk, through the gasket and into the substrate, such that tightening of the compression/retention means towards the substrate applies a compressive force on the disk to reduce the concavity thereof and retains the disk/gasket/sheet assembly attached to the substrate. Preferred use is in attaching single ply weather-proofing membrane to a roof deck.
