ABSTRACT:
A pliable flat disk of laminated construction having a thin top layer of deformable material bonded to a relatively thicker intermediate layer of pliable adhesive sealant material and a removable bottom layer of release paper covering the exposed surface of the sealant material is deformed during installation to cover and seal the head of a fastener protruding from a surface. The disk is installed and deformed by a tool having an end with a recess slightly deeper than the height of the head of the fastener and an interior slightly larger than the outer periphery of the head of the fastener. The release paper is removed to expose the adhesive sealant material and the flat disk is generally centered and stuck, adhesive side down, onto the fastener head. The tool is then centered above the disk and fastener head and pressed downwardly with a twisting motion to deform the flat disk to encompass and conform substantially to the shape of the head of the fastener and cover a surface radially surrounding the fastener head such that the deformed disk is adhered to the fastener head and to the radially surrounding surface to provide an air-tight and liquid-tight seal between the fastener head and the radially surrounding surface and to prevent relative movement therebetween. It will also cover and seal a washer if one is used with the fastener.
