| 411446000 | Including integral locking means | 14 |
| 20080240885 | Nail - A nail comprises a plurality of umbrella-shaped threads spirally formed on the shank and extended from the nail end to the head, wherein the umbrella-shaped thread includes a top face and an end edge face, in which the outer diameter of the top face is greater than the outer diameter of the end edge face, such that the nail can be nailed into a planking easily and successfully without the obstacle of the umbrella-shaped threads. While pulling out the nail, an actuating tool is used directly to rotate back the nail, so as to prevent from damaging the surface of the planking and efficiently save the time and labor. | 10-02-2008 |
| 20160186793 | COMPRESSION INDENTATION FASTENER DEVICE - An enlarged head fastener device and method for manufacturing the same is described. The enlarged head fastener device includes a shank and a head. The head extends outwardly from the shank in a transverse plane to define a head periphery. The head has an anterior side and a posterior side. The anterior side includes a bearing surface and a convergent transition portion that reinforces the head. The convergent transition portion extends between a large end adjacent the bearing surface to a small end adjacent the shank. At least one ridge formation projects from the anterior side of the head providing additional reinforcement. The ridge formation extends continuously between an outboard end positioned on the anterior side of the head adjacent the head periphery and an inboard end positioned on the shank. The head may be centered or offset relative to the shank. | 06-30-2016 |

| 20100040434 | FASTENER - A fastener for connecting two components together comprises a bolt having a head and a shaft extending integrally and downwardly from the head, an elastic member coiled around the shaft and a shell receiving the elastic member and the bolt therein and keeping the elastic member coiled around the shaft. The shell encloses the bolt and the elastic member therein to form the fastener as a single unit. The shell has a top wall against which the head of the bolt abuts and a bottom wall through which a lower portion of the shaft extends. The top wall defines a through hole to expose the head of the bolt. The elastic member is compressed between the bottom wall and the head. | 02-18-2010 |

| 20130039721 | Anchor Nail - An anchor nail comprises a nail body being cut from a metal sheet and folded into shape. The nail body has an anchor strip substantial cut from a central portion of the nail body, whereby the nail body can be stricken to pierce the work pieces together with the anchor strip by striking the striking head of the nail body, so that the striking head can be in flush with an outer surface of the work pieces whereas the striking section of the anchor strip can extend out of the outer surface of the work pieces. Thereafter, the anchor strip can be stricken to move into the work pieces to be in flush with the striking head of the nail body so that the slightly curved section can be further curved so as to anchor the work pieces. The anchor nail can enhance the combining strength of the work pieces. | 02-14-2013 |
| 411450000 | Having means engageable on underside of member being secured by fastener | 2 |
| 20090155019 | Coiled pin with flap stop - An improved coiled pin comprises a rectangular strip of metal coiled to form a substantially cylindrical pin having leading and trailing ends with a longitudinal edge on the pin exterior extending between the leading and trailing ends. The longitudinal edge has a transverse slit closer to the leading end than to the trailing end, thereby forming a flap having a width extending between the slit and the leading edge and having a free end aligned with the longitudinal edge. When the pin is fully installed and the flap is immediately adjacent the exit of the hole, the compression of the pin at the hole exit tends to expand the flap beyond such natural relaxation, approaching its neutral diameter, thereby providing a more pronounced mechanical stop against withdrawal. | 06-18-2009 |
| 20100329819 | HOLLOW WALL FASTENER - An anchor system for a hollow wall or ceiling includes an anchor portion having a flange and a penetrating portion extending from a rear surface of the flange. The penetrating portion has a fixed sleeve extending from the rear surface of the flange and a pivoting locking leg connected to the fixed sleeve by a hinge. The fixed sleeve has a sleeve opening extending longitudinally therethrough and the pivoting locking leg has a stub extending from a rear surface thereof to retain the penetrating portion rigid as the anchor is inserted into the wall or ceiling. A pin portion has a body and includes a flexible shaft extending from the body. The pin portion has an actuating element extending transversely from the shaft. The pin portion further includes an opening in the body, spaced from the flexible shaft. Once the pin portion is in place in the anchor, a secondary locking pin is inserted through the pin portion body opening into the hollow wall or ceiling to prevent rotation of the pin portion relative to the anchor portion. | 12-30-2010 |
| 411451100 | Comprising protrusion or recess on shank | 7 |

| 411453000 | Spiral rib | 2 |
| 20110014009 | IMPACT DRIVEN FASTENER - An impact driven fastener having plural shank elements formed into a unitary shank structure of helical geometry. | 01-20-2011 |
| 20110280686 | Fastener - Disclosed is a fastener comprising a central elongate shank extending between first and second ends. The first end of the shank has a tapered point. The second end a head has an annular shoulder disposed towards the second end. The fastener further comprises an opposed pair of spines extending helically along the shank and a plurality of hooks extending from each of the pair of opposed spines. Also disclosed is a protrusion extending axially with the shank from the head deformable into an anti-friction washer upon impact by a fastener driver. | 11-17-2011 |

| 20100183404 | Method for Establishing a Nail Connection and a Nail for This Purpose - A method for establishing a nail connection between two components and a nail for this purpose are described. The nail | 07-22-2010 |
| 20110318139 | TAPERED NAIL with Stablization Rings - A nail is used to fasten wood, plastic, shingles, siding and composite items together. A nail has a head and a shank or shaft. A nail is typically made of a steel or metal alloy but could be made of other materials. The nail is different from conventional nails in that its shank or shaft is not straight or twisted. The shank is tapered. The end near the head of the nail is smaller in diameter then the end that penetrates the material (the point). The shank tapers from the point progressively until it reaches a section near the head that expands to the same diameter as the shank near the point. The shank then tapers again until it reaches the head. The amount of taper varies with the different applications of the nail. The nail's shank also has rounded rings toward the head end of the shank. The rings provide the nail with stability against the host material until the host material rebounds against the tapered shank. | 12-29-2011 |

| 20090232620 | Pneumatic fastener for metal studs and related method - A pneumatically drivable fastener secures drywall or other construction material to a metal stud. Each fastener comprises a driving head; and a one piece shank component, secured at one end to the driving head. Each shank component has an axial length extending perpendicularly and longitudinally from the driving head and is divided into two or three sections: (a) an optional, solid section closest to the driving head; (b) an intermediate section with grooves that define stud cutting edges; and (c) two or more forked ends opposite the driving head. A method for fastening drywall to a plurality of metal studs is also disclosed. | 09-17-2009 |

| 20090155020 | DEFORMED SHANK FASTENER - A nail has a head, a penetrating tip and a shank extending from the head to the penetrating tip. The shank has a circumference and a longitudinal axis. A plurality of rows of deformations formed as teeth are formed in the shank extending outwardly of the shank. The rows are formed in a spiral pattern along the length of the shank from about the head to about the penetrating tip. The rows of teeth are formed parallel to one another and formed at an angle of at least 50 degrees relative to a longitudinal axis of the nail. | 06-18-2009 |
