Abstract: A fastener for a high strength connection with a substructure with a straddling dowel, drilling cylinder or nail for insertion into a substructure material, for example, of concrete, rock, wood or the like, is disclosed. At least a portion of an outer surface of the fastener means is coated with a curable adhesive.

Abstract: A process for coating a workpiece of steel with an anti-corrosive agent, comprising the steps of providing the surface of the workpiece with a chemo-mechanical layer, and chromatizing the chemo-mechanical layer, and characterized by the steps of providing the chromated layer with a further layer containing metallic components and organic binding agents, and curing the further layer by a heat treatment.

Abstract: A nail driving tool is disclosed as including a magazine (9) which, in turn, includes a guide path (7) for guiding a plurality of nails (10.sub.1, 10.sub.2, 10.sub.3. . . ) which are preferably disposed in the form of a nail strip. The guide path (7) is open at an outlet opening (2) from or through which a first or leading nail (10.sub.1) is conveyed into a discharge channel (3). A driving mechanism, such as, for example, a pneumatic driver (11) is disposed within the discharge channel (3) for driving or discharging the leading nail (10.sub.1) from or through the discharge channel (3). A cantilevered leaf spring (8) has one end thereof fixedly mounted upon the magazine (9) while the opposite free end thereof engages the second nail (10.sub.2) disposed immediately upstream of the leading nail (10.sub.1) so as to retain all of the nails disposed upstream of the leading nail (10.sub.1) while the leading nail (10.sub.

Abstract: The present invention comprises a nail driving device with a magazine for nails held together in nail strips, with a nail transport device, wherein the nail strips are pressed in the direction of a fixed stop surface by means of a spring element, and moved in the direction of the exit channel of the device mouthpiece.
