An anchor plate for securing a membrane to a sub-structure such as a roof, tunnel, tank etc. The plate has an elevated bonding platform and a enlarged central countersink, sufficiently deep to accommodate the head of a fastening screw, without the screw head protruding above the top profile of the anchor plate when the screw secures the plate to the underlying substructure. The height difference between the bonding platform and the base of the countersink together with the fact that the countersink area is wider than the head of the screw ensures that when the screw is fastened to the underlying substructure, the bonding platform does not flex. The bonding platform carries a heat activated adhesive which is inductively heated to secure an overlying membrane to the substructure.
