Abstract: A fastening device comprises a “U” shaped spacer wherein the recess of the “U” shape is captured by the upper cross bar of a staple when the staple is used to fasten a protective sheeting to an item to be stored or transported. The spacer has a flat bottom surface and a flat side surface. The flat bottom surface increases the surface area of the staple in contact with the item during transport thereby reducing the chances that the protective sheeting may become torn from the item. The flat side surface increases the surface area of the standard staple during removal of the plastic sheeting because the spacer rotates about the crossbar of the staple. This rotation of the spacer reduces frictional contact between the spacer and the protective sheeting so that when the plastic sheeting is pulled from the lumber, the plastic sheeting will pull the spacer and the staple therefrom.

Abstract: A power actuated fastener assembly for use with a power actuated gun having a broad bearing surface and a raised portion for holding a stud and raising the pointed end above the bearing surface. The raised portion or cone shape forms a gap that widens from the point of the shank to the bearing surface.

The fastener assembly can be driven in a single step with a power actuated gun without the necessity of partially driving the fastener assembly into the structure being fastened into a masonry surface. Additionally, the raised portion or cone shaped portion automatically strips away or breaks the plastic fluting commonly associated with such fasteners and is often undesirable compressed under the head of such fasteners. Thereby, a safer, more efficient power actuated fastener is obtained.

Abstract: A barbed light weight concrete fastener and plate comprises a fastener with a head and two bendable legs. Each leg has a barb and a bump protruding therefrom. The fastener is pushed through a base ply and into a roof deck of cementitious material. The legs diverge to capture a concrete wedge between them. The barbs dig into the concrete wedge to increase resistance to a pullout force. The bumps create pressure points with the cementitious material that further resist pullout. A plate may be interposed between the fastener and the base ply. The plate has a number of openings therethrough of relatively large area. The openings are filled with plugs of asphalt that adhere to the base ply. Pulling of the base ply is resisted by the plate acting against the shear areas between the asphalt plugs and the base ply.

Abstract: A roofing and siding fastener for securing underlayments, exterior insulation sheathings, and similar membranes to a substrate. The disclosure comprises a cap portion having a rectangular body with oppositely extended legs. Said legs are bent downward and have heels situated at the ends. The cap has a nail centrally inserted through the body. The installer positions the fastener over the material to be secured and strikes the nail head, thereby driving the fastener into a substrate. As the cap portion engages the material, the heels act to deflect the flattening legs over the top surface of the material instead of allowing the legs to puncture. Each flattened leg now becomes a spring-like binder which not only provides superior holding power over the prior art, they also flex upward to dampen strong winds which can blow these underlayments off. This flexibility greatly enhances the effectiveness of underlayments in a "dry-in" procedure.
