  • Patent number: 5788444
    Abstract: A fastener assembly having a stud frictionally retained within a plate. The stud having a head at one end and a point or taper at the other end. The stud having a first shank portion with a large diameter adjacent the head and a second shank portion with a smaller diameter adjacent the tapered or pointed end. The larger diameter first shank portion being frictionally or press fit into an aperture formed in the plate or washer. The plate or washer may have a flat, conical, curved, or channeled shape with a conical raised portion thereon so as to hold the fastener a relatively long longitudinal distance up along the shaft or shank of the stud. The transitional shoulder between the different diameters of the shank may be square, angled or round. The use of different diameter portions improves penetrating and holding power of the fastener assembly while permitting relatively easy penetration of a substrate.

  • Patent number: 5634756
    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. This creates a stable fastener assembly and raises the pointed end of the stud at or near the bearing surface of the fastener assembly. 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.

  • Patent number: 5632585
    Abstract: An attachment member (1) for securing very thick panels to a receiving material, such as a structural member, is formed of an axially elongated cylindrical shank (2) having a tip (3) at its leading end and a flange-like head (4) projecting laterally outwardly from the shank (2) at its trailing end. A contact pressure element (6) is located in the trailing end region of the shank (2) and is axially displaceable relative to the shank. An axially extending part arranged about the trailing end of the shank is arranged for absorbing excess energy applied to the attachment member. The shank (2) is laterally enclosed by an axially extending cylindrical sleeve (7) extending in the range of approximately 3/4 to 9/10 of the axial length of the shank. The sleeve (7) has an outside diameter (a) in the range of 1.4 to 3 times the diameter (s) of the shank (2). The sleeve (7) has a trailing end arranged to axially support the contact pressure element (6).

  • Patent number: 5624220
    Abstract: An attachment member arranged to be secured to a surface of a hard receiving material by an explosive powder charge operated setting tool is formed of a fastening element (1), such as a nail, and a prestressing element (2). The prestressing element assures a sound attachment by bridging differences in the depth to which the nail is driven. To increase its surface contacting the surface of the hard receiving material, the prestressing element is laterally enclosed at least in part by a plastics material part (3) so that the pressure of the attachment member in contact with the receiving material and the danger of tilting of the setting tool relative to the receiving material are reduced. Further, a recess (3b) is formed in the plastics material part (3) to improve guidance between the prestressing element (2) and a bolt guide (4) of the setting tool.
