applying a force to a spike type fastener 30 in a direction perpendicular to the surface of the body 20 and the plate 10 therein will drive the fastener 30 through the material of the body 20 then through the plate 10 and finally into or all the way through the remaining material of the body 20 that is located on the opposite side of the plate 10 for convenience the body 20 is shown in fig2 a 2c as a timber or piece of wood however it will be appreciated that as previously mentioned the body may be composed of many different materials and need not be composed of a single type of material but rather can have layers or other configurations that may include for example an outer cover of a different material in this example the plate 10 deforms as some of the plate material is moved by the fastener 30 into the material in which the fastener is embedded the plate 10 will provide some additional resistance to insertion but this can be controlled by appropriate selection of plate material and thickness the material of the body 20 that is displaced during insertion of a fastener 30 and the deformation of the plate 10 can yield two modes of increased resistance to extraction non buckling and buckling in fig2 a the spike type fastener 30 has not yet been driven into a section of the body 20 the tip of the fastener 30 is perpendicular.
