Including Settable Material Patents (Class 411/258)
  • Patent number: 5263804
    Abstract: A construction anchor for mounting an object on a structure of masonry, concrete, metal or the like includes a metal anchoring portion and a plastic cap. The anchor is adapted to be inserted, metal end first, into a pre-drilled adhesive-filled hole. The cap has a flange that is larger than the hole diameter, so that the anchor may be inserted and seated in the hole at a consistent depth. When the adhesive has set, a screw or bolt is inserted through the plastic cap to engage the threads in an internal bore in the anchoring portion. The plastic cap serves not only to determine the depth of the anchor in the hole, but also to prevent adhesive and other material from entering the threaded interior of the anchor prior to use.

  • Patent number: 5253965
    Abstract: A fastener suitable for joining two or more plastic or metal panels together under automated manufacturing conditions. The fastener has a piercing end for forming its own passage through the panels so as to avoid the need for a pre-drilled hole. Disposed near the piercing end are one or more rigid barbs which extend obliquely from the shank toward the head of the fastener. The barbs create an interference with the adjacent panel to secure the panels. The fastener further incorporates an adhesive strip which serves to adhere the fastener to the panels in a manner that prevents both rotation and axial displacement of the fastener relative to the panels. The fastener is particularly adapted for permanently joining two or more panels where access to both sides of the joined panels is either impracticable or undesirable, such as when a body panel of an automobile is to be fastened to the automobile's frame.

  • Patent number: 4657460
    Abstract: The present invention relates to improvements in a self-bonding fastener and to a novel method of curing the bonding material during assembly line fabrication of sheet metal products. The fastener includes a headed self-threading screw member having its head undersurface formed with an annular axially extending lip. An upper portion of the screw thread is precoated with a thermo-setting adhesive which, when heated, will uniformly bond the fastener to a sheet metal plate. As the fastener is threaded through an undersized hole in a sheet metal member, such as an automobile body, the adhesive reliquifies and is stripped from the screw thread. The adhesive is then re-deposited uniformly to completely fill a closed chamber defined between the head undersurface and the opposed sheet metal surface sealed on its periphery by the annular lip which defines the axial dimension of the adhesive thickness.
