Fastener, to hold insulating materials/films at a surface, has a plastics base body to take a metal component and a nail in a robust structure, firmly held at the surface

摘要

The fastener has a plastics base body (1), with an opening through it to take the fastener (3) e.g. a nail, to secure the base body to the supporting surface (5). The base body has an embedded metal component (4), with the nail through it, to hold the fastened body against the surface. The metal component projects slightly from the body, to give a gap (6) between the body and the surface.
