  • Patent number: 10865824
    Abstract: An asymmetric thread impact drivable screw and clip for use with a power impact device for penetrating wood fibers while minimizing cut fibers. The screw includes an impact head and a conical shaped tip having a ballistic insertion angle at the ends of a shank. The shank defines asymmetrical threads with an insertion flank having a long side at a slide angle peaking at a crest supported by a catch flank positioned at a grip angle. Varying tool accepting recess are taught for the head along with multiple thread sections. A mushroom compaction thread section is also taught.
    Type: Grant

  • Patent number: 10751863
    Abstract: A fastener driving tool magazine and nose piece for use with a fastener with a preinstalled elastomer beneath the head of the fastener. A magazine structure for avoiding damage to the elastomer is taught and a birds beak fastener guide is taught for installing the fastener while still avoiding damage to the elastomer.

  • Patent number: 9630305
    Abstract: The present invention is directed to a nail gun outrigger for stabilizing the roll, pitch, and yaw of a nail gun. The outrigger is connected to the distal end of the magazine away from the driving head. For the preferred embodiment, the outrigger includes one or more outriggers that extend perpendicular to the axis of the magazine with feet contacting the nailing surface to control the pitch, roll, and yaw of the nail gun position to obtain consistent perpendicular installation of elastomer sealing pneumatic nails into preformed roofing panels installed on a wooden frame or substrate.
