Abstract

A method of installing a fastener into a structure, comprising the steps of providing a fastener having a pin member including an elongated shank having a first end, a second end opposite the first end, a cylindrical shank portion having an outer surface, a head located at the first end of the elongated shank, the head including a bearing surface located on the underside of the head, and a threaded portion located at the second end of the elongated shank and a seal element adapted to be positioned on the pin member such that the seal member is juxtaposed with the bearing surface of the head of the pin member; and installing the fastener into the structure in an installed position.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method of making a fastener, comprising the steps of:
 providing a pin member including an elongated shank having a first end, a second end opposite the first end, a cylindrical shank portion having an outer surface, a head located at the first end of the elongated shank, the head including a bearing surface located on the underside of the head, and a threaded portion located at the second end of the elongated shank; and   attaching a seal element to the pin member in a position that is juxtaposed with the bearing surface of the head of the pin member.   
     
     
         2 . The method of  claim 1 , further including the step of coating at least a portion of the pin member with a coating. 
     
     
         3 . The method of  claim 2 , wherein the coating is a metallic coating. 
     
     
         4 . The method of  claim 3 , wherein the metallic coating is selected from the group consisting of gold, silver, and copper. 
     
     
         5 . The method of  claim 2 , wherein the coating is made from a material having an electrical conductivity higher than 20% IACS. 
     
     
         6 . The method of  claim 2 , wherein the coating step includes coating the head of the pin member with the coating. 
     
     
         7 . The method of  claim 2 , wherein the coating step includes coating the outer surface of the cylindrical shank portion with the coating. 
     
     
         8 . The method of  claim 7 , wherein the coating step includes coating the head of the pin member with the coating. 
     
     
         9 . The method of  claim 7 , wherein the coating step includes coating the threaded portion of the pin member with the coating. 
     
     
         10 . The method of  claim 2 , wherein the coating step includes coating the pin member fully with the coating. 
     
     
         11 . A method of installing a fastener into a structure, comprising the steps of:
 providing a fastener having a pin member including an elongated shank having a first end, a second end opposite the first end, a cylindrical shank portion having an outer surface, a head located at the first end of the elongated shank, the head including a bearing surface located on the underside of the head, and a threaded portion located at the second end of the elongated shank and a seal element adapted to be positioned on the pin member such that the seal member is juxtaposed with the bearing surface of the head of the pin member; and   installing the fastener into the structure in an installed position.   
     
     
         12 . The method of  claim 11 , further including the step of coating at least a portion of the pin member with a coating. 
     
     
         13 . The method of  claim 12 , wherein the coating is a metallic coating. 
     
     
         14 . The method of  claim 13 , wherein the metallic coating is selected from the group consisting of gold, silver, and copper. 
     
     
         15 . The method of  claim 12 , wherein the coating is made from a material having an electrical conductivity higher than 20% IACS. 
     
     
         16 . The method of  claim 12 , wherein the coating step includes coating the head of the pin member with the coating. 
     
     
         17 . The method of  claim 12 , wherein the coating step includes coating the outer surface of the cylindrical shank portion with the coating. 
     
     
         18 . The method of  claim 17 , wherein the coating step includes coating the head of the pin member with the coating. 
     
     
         19 . The method of  claim 17 , wherein the coating step includes coating the threaded portion of the pin member with the coating. 
     
     
         20 . The method of  claim 13 , wherein the coating step includes coating the pin member fully with the coating. 
     
     
         21 . The method of  claim 11 , wherein the structure includes a composite material. 
     
     
         22 . The method of  claim 21 , wherein the structure is substantially made from the composite material. 
     
     
         23 . The method of  claim 21 , wherein the structure is partially made from the composite material. 
     
     
         24 . The method of  claim 11 , wherein the structure includes a metallic material. 
     
     
         25 . The method of  claim 24 , wherein the metallic material is aluminum. 
     
     
         26 . The method of  claim 24 , wherein the structure is made substantially from the metallic material. 
     
     
         27 . The method of  claim 24 , wherein the structure is made partially from the metallic material. 
     
     
         28 . The method of  claim 11 , further comprising the step of trimming the seal element flush with the structure. 
     
     
         29 . The method of  claim 28 , wherein the trimming step includes sanding the seal element. 
     
     
         30 . The method of  claim 28 , further comprising the step of providing a metallic mesh on an outer surface of the structure, wherein when the fastener is in its installed position, the sealing element of the fastener is in direct physical and electrical contact with the metallic mesh. 
     
     
         31 . The method of  claim 30 , wherein the seal element includes a sealing portion having a first side and a second side opposite the first side, a lip extending from the first side of the sealing portion, the lip being in direct physical and electrical contact with the metallic mesh. 
     
     
         32 . The method of  claim 31 , wherein the metallic mesh is made from copper.
