Abstract: An impact nailing arrangement having a nail with integral pointed target-penetration and securing forward section, rear hammer section, and medial compression shear section, the forward section having a threaded object-securing surface rearwardly of its pointed forward target-securing end. The nail is propelled into a target in the preferred embodiment by any one of several illustrated latent energy means, and the forward section is secured by initial point penetration and subsequent compression shear of the medial shear section to enable the hammer section to impart a secondary securing impact to the forward section. Various alternative propulsion arrangements including electrical actuation of a powder charge, spring actuation, and valved pressurized gas, are disclosed.
